Instructions for Triangle Coaster Crochet Pattern

Foundation Row

Using Color A, chain 19.

Tip: The turning chain counts as a stitch, so you’ll have 18 stitches plus the turning chain.

Row 1

Starting in the second chain from the hook, work 1 single crochet (sc) in each chain across.

Stitch Count: 18 sc

Chain 1 and turn.

Row 2

Work 1 single crochet in each stitch across.

Stitch Count: 18 sc

Chain 1 and turn.

Rows 3–24

Repeat Row 2 until you have completed 24 rows total.

At the end of Row 24, fasten off both colors

Working the Colorwork Chart

Begin at the bottom-right corner of the chart.

Work the chart in single crochet, following these guidelines:

• Odd-numbered rows are read from right to left.
• Even-numbered rows are read from left to right.
• Change colors whenever the chart indicates.
• Carry the unused yarn across the top of the previous row, crocheting over it as you work. This keeps the carried yarn hidden inside your stitches and helps create a neat back.

Continue following the chart until all 24 rows are complete.

Beginner Tips

• ✔ Keep both yarns attached while working the chart—you don’t need to cut the yarn every time you change colors.
• ✔ Change to the new color during the last yarn over of the stitch before the color change for clean-looking color transitions.
• ✔ Carry the unused yarn loosely so your fabric doesn’t pucker.
• ✔ Count your stitches at the end of each row to make sure your project stays the correct width.

Congrats your triangle coaster crochet pattern is finished and you will love how your coaster turned out.
