I'm just starting one of my first ever crochet patterns - some Alice in Wonderland inspired fingerless gloves from Tiny Owl Knits, and am confused on the first step! The pattern says "ch 20, turn; Sc in each chain (20 sc)" Shouldn't you chain 21 if you want to make 20 sc on your first row? If not, how do you sc in the first ch from the hook? When I try, it doesn't work properly, and I get a really weird stitch. Any guidance would be much appreciated. Cheers, Sophie.
