I'm working on my first project, a simple garter stitch scarf, but as I progress the number of stitches increases, and the scarf keeps getting wider and wider. This is exactly the problem I enountered when I tried knitting a few years ago and caused me to stop knitting, but this time I want to get past it. When I mention this to experienced knitters, they always say, "Oh, I know what you're doing," but I don't. Grrrr! Any suggestions?
