Hi. I’m new here. I’ve been knitting off and on for a few years. Mostly make afghans and dishcloths. I’m making an afghan with blocks. The blocks are 9 to 10 inches square. The directions say to single crochet evenly spaced around the block with 3 sc in the corners but it doesn’t say how many crochet stitches to put around. I finished knitting the first block and it has 44 stitches top and bottom. I used a selvedge edge on the sides and so it has 33 chain stitches. I’d like to make the edging all the same number of sc on all the blocks so I can put them together. How do you figure out how many sc to put. I’ve done edging around blocks before but they told you how many to put. Thanks for any help.
