I have counted my stitches (all 113 of them) and they are intact, but I have a spot where I have the 'ladder' effect going on. Could I have dropped a stitch but still have the correct number of stitches? And how do I fix it!? I have loose thread there and I've gone over it with 2 more rows thinking it would repair but it hasn't. I'm about to take the last 3 or 4 rows off and start again..
