Work your first flat swatch
Twenty single crochets across, row after row. The exercise that teaches turning, counting and straight edges.

A swatch is a small practice square. It builds muscle memory, and you will need to make swatches later to check gauge. For this one you need worsted yarn and a 5 mm hook.
Row 1
- Chain 21.
- Insert the hook into the 2nd chain from the hook (skip the first chain).
- Yarn over, pull up a loop, yarn over, pull through both loops. That is one single crochet (sc).
- Work 1 sc into each chain across. You should have 20 sc.
Row 2 and onwards
- Chain 1 (this is the turning chain; it does not count as a stitch).
- Turn your work so the yarn is on the right, if you are right-handed.
- Work 1 sc into each stitch across, going under both loops of the V at the top of each stitch. You should have 20 sc.
- Repeat until your swatch is about 10 cm (4 in) tall.
Getting straight edges
- Edges getting narrower? You are skipping the last stitch. Work into the very last stitch of every row.
- Edges getting wider? You are working an extra stitch into the turning chain. Skip it.
- Count every row for the first few rows. It is faster to fix a mistake early.
When you have a square of neat rows, you can work almost any pattern that uses single crochet, like the Stacked Coaster Set, once you have learned the magic ring.
