October Knot

This beautiful square, October Knot, features two circles that are being wrapped with a continuous loop that goes over and under in a Celtic knot type way. I love how intricate it looks!

As always, these large Celtic knot squares can be crocheted using one of two techniques: interlocking crochet or center-out, overlay mosaic crochet. You’ll receive the full written pattern and charts for both techniques.

If you’re new to these colorwork techniques, start with my tutorials.

We are nearly through with this series of squares (2023 is almost over!) but if you’re just joining us, start at the landing page for the Celtic knots series.

NEW! Third Option!

In addition to the original interlocking crochet option and center-out overlay mosaic crochet option, as of November 2023 I’ve now added a bottom-up overlay mosaic crochet option!

This version of each Celtic knot square will require you to cut your yarn at the end of each row. The fringe that gets created can either be a style feature or hidden in an envelope border. Some people choose to weave in the ends instead.

Or you can use this new file for tunisian mosaic crochet if you don’t want to deal with the cut ends on the sides.

October Knot’s Inspiration

When I was researching Celtic Knots I came across this worn stone with a neat design and that became the basis of my design for October Knot.

This carved celtic knot is found at the doorway to the St. Mary Tower in Cahir Priory, Cahir, County Tipperary, Ireland.

Interlocking Crochet

The interlocking crochet version is done from the bottom-up.

All of the Celtic Knots squares are on a chart size of 81 x 81. This means they begin with 40 windows in the foundation row and will finish to about 20″ square.

Interlocking crochet / LFM crochet file includes:

– line-by-line instructions- instructions on reading a chart
– a one-page chart

Interlocking Crochet Details

  • Chart is 81 x 81
  • Gauge: 8 (dc, ch) x 8 rows = 4”
  • 20″ x 20″ / 51cm x 51cm
  • 4.5 mm hook (US7)
  • Worsted weight yarn (490 – 565 yards total)
    • Main color (MC) (knot) – 250 yards plus 75 for optional border
    • Accent color (AC) (background) – 240 yards

Center-Out Overlay Mosaic Crochet

The original overlay mosaic crochet version is done from the center-out so we don’t have to worry about any cut ends when we join our squares!

The mosaic crochet charts have been adjusted from their interlocking crochet counterparts. They are solid (there are no interlocking mesh dots on it) and they do not have the unnecessary border lines.

The full chart is 77 x 77 and will finish to about 19″ square. Take note, you’ll receive the top 1/4 of the x-marked chart that gets repeated for all 4 sides of the square.

Center-Out Overlay Mosaic Crochet file includes:

– line-by-line instructions
– instructions on reading a chart
– a one-page chart marked with X’s for mosaic crochet

Mosaic Crochet Details

  • Chart is 77 x 77
  • Gauge: 16 sc blo stitches x 16 rows = 4”
  • 19″ / 48cm
  • 5 mm hook (H-8)
  • Worsted weight yarn (570 yards)
    • Main color (knot) – 240 yards
    • Contrasting color (background) – 330 yards

I just love the color combo of dark blue with gold! CrochetCarob’s photos are always fantastic!

Bottom-Up Overlay Mosaic Crochet

The additional bottom-up overlay mosaic crochet version can be done using Tunisian mosaic crochet if you’re trying to avoid an envelope border. Or you can weave in the cut ends. Another option is to crochet the squares together as you make them – create your foundation row as wide as three squares, for example, and crochet row 1 of all three squares, one after another, without cutting between them.

The bottom-up charts use the same solid image as the center-out mosaic crochet charts.

Gauge when worked from the bottom-up will be slightly different than when you work from the center-out.

You’ll receive both a single-page chart and a multi-page chart. Both charts have x’s marked on them for the dropped double crochets.

Bottom-Up Overlay Mosaic Crochet file includes:

– line-by-line instructions
– instructions on reading a chart
– a one-page chart marked with X’s (good for viewing on a screen)
– a four-page chart marked with X’s (better for printing)

Bottom-Up Mosaic Crochet Details

  • Chart is 77 x 77
  • Gauge: 14 sc blo stitches x 15 rows = 4”
  • 22″ x 21″ / 56cm x 52cm
  • 5 mm hook (H-8)
  • Worsted weight yarn (600 – 850 yards)
    • Main color (knot) – 250 yards
    • Contrasting color (background) – 340 yards
    • Optional envelope border – 250 yards
