2025 October Mystery Pattern
This is my 4th mystery design! You get to choose which technique you want to use (interlocking or mosaic) and then you grab a little bit of spare yarn and follow the written pattern.
You can’t use the chart for the mystery pattern because it would show you the design.
We will give everyone the rest of October to crochet and then on November 1st, 2025 we will reveal our squares!
Exposed Mysteries?
If you’re curious about my previous mystery designs you can check them out on the October Mystery landing page.
Free or Paid
View the free written pattern here online. No charts because that would ruin the mystery.
Later, after the mystery is gone, I’ll post a printable PDF for sale in my shops. It will include charts along with the written patterns for both techniques.
Purchase Links
As we’ve now reached November, this year’s mystery design is no longer a mystery!
You can now purchase a printable PDF that includes the fully written pattern AND the chart! You’ll get both techniques.
2025 October Mystery Pattern
For some crocheters, this “mystery” is just a nuisance.
It is absolutely fine if you want to wait until November, see everyone’s squares, and then decide if it’s something you want to put time and effort into.
For others who like the surprise, I hope you’ll enjoy crocheting and wondering what it is that is appearing!
Color Choice
Ok, you won’t tell us anything about the design, so how am I supposed to choose colors?
My usual color recommendations still apply: make sure there’s good contrast between your two colors (take a black & white photo to see if it will work), try to avoid multi-colored or variegated yarn, and I think it looks best when the background is a lighter color than the image I’ve drawn.
The Main Color / first color used will be the design I’ve drawn. The background color is quite predominant in this design.
I used dark purple as the main color in my interlocking crochet sample; I paired it with a light blue for the background.
With my mosaic crochet sample I chose black as the main color and paired it with Red Heart Super Saver Retro Stripes. This yarn gradually changes colors but they are all light enough to contrast well with the black yarn. And the change is slow enough that it doesn’t distract from the image.
Some more color combinations from my testers (main color listed first): sand/white, dark blue/variegated blue, grey/light rainbow, pink/black, yellow/white, blue/white, green/blue.
Important Details
Each design comes with the fully written pattern and charts for two colorwork techniques: interlocking crochet and overlay mosaic crochet.
Yarn weight and hook size can easily be adjusted; just keep in mind your finished project will use a different amount of yarn and be a different finished size. It is easiest to join squares of the same size: https://ashleeslint.com/small-squares/.
Click here to go to my tutorials for these crochet techniques.

Interlocking Crochet: October 2025 Mystery Pattern
About the use of brackets: https://ashleeslint.com/2020/08/29/brackets-in-crochet-patterns/
Surprise!
There’s no picture or chart included here because this design is supposed to be a mystery! See past year’s designs at https://ashleeslint.com/2023/11/07/october-mystery-patterns/
Make sure there is good contrast between your two yarn colors, but other than that you can really use whatever colors are your favorites! It is a small design so you’re not wasting too much time and energy on a mystery that you might not like.
The predominant color is the background which uses the AC (2nd color). The MC is the design I’ve drawn but the lines are simple and thin.
Yarn weight and hook size can easily be adjusted, just keep in mind your finished project will use a different amount of yarn and be a different finished size.

KEY
AC = accent color: the background color
ACB = put AC yarn to the side facing away from you
ACF = bring the AC yarn to the side facing you
B = double crochet (dc) behind, and chain 1
Back = the side not facing you
ch = chain
dc = double crochet: yarn over, insert hook, yarn over, pull up loop, *yarn over, pull through two loops* twice
EB = end stitch in back: using AC, dc into the last AC window, working behind MC
EF = end stitch in front: using AC, dc into the last AC window, working in front of MC
ES = end stitch: dc into the last window space
F = double crochet (dc) in front, and chain 1
Front = the side currently facing you
MC = main color: the mystery image
RS = right side: the side of your work that will show the finished design
sk = skip a stitch
sc = single crochet: insert hook, yarn over, pull up loop, yarn over, pull through both loops
tr = treble crochet: yarn over twice, insert hook, yarn over, pull up loop, *yarn over, pull through two loops* three times
WS = wrong side: the back of your project
Remember, each color is worked into itself only and there is a chain space between each double crochet
Don’t confuse RS / WS with Front / Back
Foundation Rows
STEP 1
Using MC create 20 windows:
A. I prefer the chainless technique (chain 5, dc into first stitch, chain 1, tr into same space, *chain 1, tr into 2nd part of the previous tr* repeat as many times as needed).
B. Alternatively, you can chain 43, then DC in 5th chain from your hook. *Ch 1, Sk 1, DC* repeat until the end. Place stitch marker so your work doesn’t unravel.
See how at https://youtu.be/_3So3Pe8GWc?t=100.
STEP 2
With your AC, chain 41. Place MC windows on top of this chain (make sure the end with the stitch marker is at your left) then pull the tail of your AC through the window on the right end (see picture above). DC through the back of the next window into the 5th chain from your hook.
See how at https://youtu.be/_3So3Pe8GWc?si=Lmu8M9F60Hv6zRYz&t=321
Short sample showing how to put the gold AC tail through the dark purple MC trellis
STEP 3
Using your AC, *Ch 1, Sk 1, DC through the back* repeat to end. Place stitch marker so your work doesn’t unravel. Both stitch markers should be on the same end.
Turn your work and continue at row 4.

Let’s keep these projects a secret until November 1, 2025!
Revised SC border
Chain 1, put 1 sc in the MC gap, and then the second sc should pick up one loop of the AC as well as going through the MC gap. Do this in each gap on all four sides. Add an extra chain 2 on the corners.
Other SC Border Option
Chain 1, put 2 sc in each gap on all four sides. Add an extra chain 2 space in each corner (corner gap will have 2sc, 2ch, 2sc).
Overlay Mosaic Crochet: October 2025 Mystery Pattern
About the use of brackets: https://ashleeslint.com/2020/08/29/brackets-in-crochet-patterns/
Surprise!
There’s no picture or chart included here because this design is supposed to be a mystery! See past year’s designs at https://ashleeslint.com/2023/11/07/october-mystery-patterns/
Make sure there is good contrast between your two yarn colors, but other than that you can really use whatever colors are your favorites! It is a small design so you’re not wasting too much time and energy on a mystery that you might not like.
The predominant color is the background which uses the CC (2nd color). The MC is the design I’ve drawn – but the lines are simple and thin.
Yarn weight and hook size can easily be adjusted, just keep in mind your finished project will use a different amount of yarn and be a different finished size.

KEY for Mosaic Crochet
CC = Contrasting Color: white in chart, background color
ch = chain
DC = double crochet: yarn over, insert hook, pull up a loop, *yarn over, pull through two loops* twice
dc = dropped double crochet: skip next single crochet, and instead double crochet into Front Loop of stitch in the row below
ES = End Stitch: single crochet under both loops, chain 1, cut yarn and pull through tightly
FSC = foundation single crochet: chain 2, insert hook in first chain, *yarn over and pull a loop through, yarn over and pull through one loop (chain made), yarn over and pull through remaining 2 loops (SC made); to make the next stitch insert your hook into the chain made previously and repeat from *
JS = Joining Stitch: create slip knot, insert hook under both loops, complete a normal single crochet
MC = Main Color: blue in chart, first color used
SC = single crochet: insert hook, pull up a loop, yarn over, pull through both loops on hook
sc = SC into Back Loop only
Remember to skip the same number of stitch(es) behind your dc(s) before doing your next sc
Dropped Double Crochet uses front loop, 2 rows down (blue into blue). Skip the green single crochet that will hide behind this stitch.
Single crochet in back loop only.
Mosaic Crochet Technique
- Remember to skip the same number of stitch(es) behind your dc(s) before doing your next sc
- The front of your work is always facing you (this is the right side, the side showing the design)
- You are always working from the right to the left
- You tie on a new yarn at the beginning of each row and cut it at the end
- Tails don’t need to be longer than an inch and a half
- Yarn colors can be anything you like. They need to contrast well and be the same weight (size / thickness)
- I prefer using a Foundation Single Crochet to create my foundation row because then I have tails on both sides of my work just like all my other rows will have
- Even-numbered rows use MC; odd-numbered rows use CC
Foundation Row (Row 0): use Main Color (MC) / background color
Use the foundation SC technique to create 39 FSC.
Or chain 40, SC in 2nd chain from hook and SC all the way back across. Cut and tie off.
For row 1, switch to Contrasting Color (CC)

Finishing Touches
Trim the fringe, if needed.
Add optional envelope border (YouTube tutorial: https://youtu.be/P-uXHjwTFeE). Instructions at the end of this pattern show a double crochet envelope, but you may prefer to use single crochet or single crochet in back loop only.
