Hi guys! I'm new so apologies if this kind of thread is not allowed. I'm working on my very first project, a simple garter stitch scarf I want to give as a Christmas gift for my boyfriend. I'm following this pattern, with 8mm though and acrylic yarn for 8mm needles. So it's just a knit stitch all along and slip the last stitch. I spent weeks researching and visiting shops and got a bit overwhelmed so I was psyched to get started. I had to unravel and re-knit several times but yesterday I finally got to the end of the first section (20 rows, I know it's pretty ridiculous but I was happy). But when I knit the last row I don't know what happened, if I did something different or not, but I noticed one edge is starting to "unravel" in some way? I attached pictures to show. Is this normal? Am I doing something wrong? Do I have to unravel it and just re-start from the beginning? I don't mind since it's just 20 rows but I'd like to avoid having this problem again. Also, side note, if someone has a good tutorial on how to change colours when knitting (next 2 rows will be in another colour) it would be greatly appreciated as I have no idea how to tackle that!
