(1) The picture is a little blurry, but you get the idea - stockinette or reverse stockinette can face out, and there is this 5-edge stitch that unravels to become a fringe in the end.(2) I used a stockinette stitch with a twist of double rib and a pretty gusset stitch in super soft 4 ply.(3) I'm thinking that my square will be a simple garter stitch with the word u251cu00f6u251cu00e7u251cu2510loveu251cu00f6u251cu00e7u251cu00fb in stockinette .(4) Many patterns will tell you to work in stockinette stitch without explaining what that is.(5) Use an 11-stitch cable with 2 reverse stockinettes and a rib on either side and then 4 stitches of garter stitch.
