What's this F1, F2 and M1-M2 connection stuff you wonder? Well, it is to explain how many and which stitch loops from the previous row are picked up, when needlebinding rows. It can also be used to describe decreases. Photos of [yet to be determined stitch and] connection types by Elsa, posted 2011-10-05 in her blog The Medieval Elsa.
