Letter F: Knitted alphabet square instructions

Abbreviations:
- CO: cast on
- RS: right side
- WS: wrong side
- st(s): stitch(es)
- k: knit
- p: purl
The Pattern: General Instructions
- Cast on sts
CO 43 sts with US 7 (4.5 mm) needles.
I always cast on and bind off stitches with larger needles than I use for the main work. This prevents my cast on and bind off rows from being too tight. - Garter stitch bottom border
With US 6 (4 mm) needles, knit 4 rows.
Slip first stitch on every row as if you were to knit it, but without knitting it (except on the first row). It will form a neat and sturdy border. - Main pattern with garter stitch side borders
Continue working the next 55 rows as follows:
4 garter sts, F knitting pattern over 35 sts, 4 garter sts
You can follow either the row-by-row written instructions or the chart below for the F knitting pattern. - Garter stitch top border
Knit 4 rows.
- Bind off
Bind off all sts with a US 7 (4.5 mm) needle. Cut yarn and weave in ends.
- (Optional) Blocking
Block your square to its final measures.
