As I’ve written in the past, I’m a BIG stitch marker user. So even though the pattern doesn’t call for stitch markers, I use them anyway.
This is an example. I love how easy the Fish Lips Kiss heel pattern is. But I like to put a stitch marker after EVERY twin stitch I make. By using the same color, I can even easily see if I’m on the knit side or the purl side if I stop knitting before the heel is completed. If there isn’t a matching set of markers, I’m on the purl side.
Yes, I should be able to recognize the twin stitch before I get to it so as to know where to make the next twin stitch. But a marker makes it idiot proof. I like big red flags!!
I’m happy to have found a system that works for me. I find heels stressful enough so anything that makes knitting a heel easier is welcome.
