I feel like an idiot asking this questions after making I don't know how many projects over the past 8 years. Whenever a pattern says M1, I pull up a stitch from the horizontal yarn between the stitch I just knitted and the next one on my needle. However, my project ends up with a hole there. More of a gap, really. I am left-handed and don't know if that has anything to do with it, but does this happen to anyone else? Am I doing it wrong?
