Grandmother’s Afghan with mirrored increases and decreases.
Not my grandmother’s afghan :)
Notes: - The stitchmap in the swatch photo resembles what the fabric looks like. What it takes to actually achieve that is counterintuitive. - sl1-k2tog-psso = sssk - M1R purled through back loop to avoid an extra twist
Shown with a cast-on count of 21 stitches.
