Stitches and Abbreviations (US Terms)
You can click on any of these links for a step by step tutorial on how to crochet these stitches.
ch(s) – chain(s)
rep – repeat
sc – single crochet
st(s) – stitch(es)
Notes
In this tutorial I use the single crochet, but you can easily crochet this triangle with double crochet too.
The triangle pattern in rows (both of them) includes a row of single crochets between rows of either increases or decrease. This creates a gradual, taller triangle.
To crochet a triangle with sharper angles, skip the regular rows and either increase or decrease every row.
