I honestly don't know what's going on with my gauge. So I'm working on a sweater for my dad for Christmas and I'm suppose to have 20 stitches to 4 inches. On sz 8 needles I had 19 stitches to 4 inches. So, I went down a size to 7s, now i have 18 sts to 4 inches. How did I even do that? Yeah, I'll have to see if I can find what I need to do this. But I don't see how I'm looser on smaller needles. Any thoughts?

Bright Blessings!
