I know of two increases: the bar increase and the m1. Earlier today I began knitting an armwarmer, no pattern in particular, in stockinette and I started using the m1 increase. Perhaps it's just me but it left a bit of a hole below which I wasn't happy about. SO I used the bar increase which... well, you know, left a little bar there. Here's my questions: 1) Do you think I was doing m1 wrong?; 2) Is there an increase out there that won't leave a trace?
