Welcome to the beginning of my MusicCAL 2021 (Crochet-A-Long)! This post includes the interlocking pattern and the overlay mosaic pattern (click to skip ahead to the patterns). If you’re new to these techniques, check out my tutorials on YouTube!

The free pattern begins here and a new section will be released each week. If you’d prefer, you can grab the FULL pattern (with a chart!) on Ravelry or Etsy. Get 20% off for the duration of this CAL (no code required, add to cart to see the discount, expires June 24, 2021). Thank you for supporting your designer! <3 If you enjoy this free version of the pattern you could share the link and invite your friends to visit me here!

The pattern is written in a way that allows you to easily choose how wide you want your project to be. The decorative border on each side remains the same, but the inner design can be repeated (it is marked with *s).

For example, in each row of the mosaic version there is a Joining Stitch (JS), 9 stitches, *52 stitches*, 10 stitches, and an Ending Stitch (ES).

If you ignore the *s you will have 73 stitches across and I call this a table runner. My interlocking sample is a table runner, using purple as the Main Color (MC) and yellow as the Accent Color (AC).

You could repeat the 52 stitches in between the stars to make your project wider. Four repeats will make a big throw blanket: JS, 9 stitches, *52 x 4 = 208*, 10 stitches, ES for a total of 229 stitches wide.

My mosaic sample is just two repeats long. I am using Bernat Handicrafter cotton for this one, so I prefer a 5 mm hook. My baby girl likes the texture and wouldn’t let me get a clear photo, hope you don’t mind her baby toes.

Hopefully these tables will help you decide how much yarn you need:

Interlocking Crochet

Key (US terminology)

AC = accent color (white on chart)

MC = main color (black on chart)

RS = right side: the side of your work that will show the finished design

WS = wrong side: the back of your project

Back = the side not facing you

Front = the side currently facing you

ch = chain

sk = skip a stitch

sc = single crochet: insert hook, yarn over, pull up loop, yarn over, pull through both loops

dc = double crochet: yarn over, insert hook, yarn over, pull up loop, *yarn over, pull through two loops* twice

tr = treble crochet: yarn over twice, insert hook, yarn over, pull up loop, *yarn over, pull through two loops* three times

B = double crochet (dc) behind, and chain 1

F = double crochet (dc) in front, and chain 1

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

ACB = put AC yarn to the side facing away from you

ACF = bring the AC yarn to the side facing you

Hints

Remember, each color is worked into itself only and there is a chain space between each DC.

Don’t confuse RS / WS with Front / Back.

Foundation Rows (36 MC stitches, 35 AC stitches) (see table above to adjust width)

1. Using MC create 35 windows:
   1. I prefer the chainless technique (chain 6, dc into first stitch, chain 1, tr into same space, *chain 1, tr into 2^nd part of the previous tr* repeat as many times as needed).
   1. Alternatively, you can Ch 71 + 3 (or 4 if you chain tighter than me), then DC in 6^th (or 7^th) chain from your hook. *Ch 1, Sk 1, DC* repeat until the end. Place stitch marker so your work doesn’t unravel.
2. With your AC, Ch 71 +1 (or 2 if you chain tighter). 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 6^th (or 7^th) chain from your hook.
3. *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.

See you next week for the next section of the pattern!

~*~*~*~*~ Or, begin here if you’re using the overlay mosaic technique! ~*~*~*~*~

Mosaic Crochet

Key (US terminology)

MC = Main Color: black in chart

CC = Contrasting Color: white in chart

ch = chain

SC = single crochet: insert hook, pull up a loop, yarn over, pull through both loops on hook

sc = SC into Back Loop only

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

JS = Joining Stitch: create slip knot, insert hook under both loops, complete a normal single crochet

ES = End Stitch: single crochet under both loops, chain 1, cut yarn and pull through tightly

Remember to skip the same number of stitch(es) behind your dc(s) before doing your next sc

Technique

• 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 (opposite for left-handed crocheters)
• 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 (unless you want to use them as fringe, like on scarf)
• Yarn colors can be anything you like
  • They need to contrast well (try a black and white photo to see if they are too similar)
  • They need to be the same weight (size/thickness)
• I prefer using a chainless SC to create my foundation row because then I have tails on both sides of my work just like all the other rows will have
• Even-numbered rows use MC; odd-numbered rows use CC

Foundation Row (Row 0): use Main Color (MC) (black on the chart)

Use a chainless SC technique to create 71 +2 SC. Or, chain 71 +3, SC in 2^nd from hook and all the way back across. Cut and tie off. To adjust width, add 52 stitches per repeat; see table above.

Switch to Contrasting Color (CC) {Even- rows use MC; odd-numbered rows use CC}
