This may have already been asked, but I searched and could not find it. I recently made a dishcloth afghan for my great-nephew (all knit stitches, done on the bias). Somewhere in the middle of the decrease side, I goofed up at the edge close to the yarn over, and ended up with a hole where one didn't belong. It wasn't a yarn-over or a dropped stitch, but I think I may have picked up a strand in my stitch or grabbed a strand from the stitch below? I don't know how to figure out what I did and how to fix it correctly. . .I got it fixed, but it wasn't right. I tried about 6 times, and then gave myself permission to accept that I got the hole closed and just finish the darned thing. I was really unhappy that I had the ugly fix right along the edge. I can fix mistakes anywhere else in the piece, but let me mess up in the border or right next to it where the decreases are, and I get totally lost in the stitch anatomy and can't make it look right again to save my life!
Can someone explain the logic of 1) figuring out exactly what I did and 2) exactly how to understand what those decreases are doing and how to drop them and pick them back up correctly in a bias project?
