I’m in the camp of those who don’t hate seaming, but don’t love it either. I would rather knit and have it done when I’m done knitting, but I don’t go out of my way to avoid it like the plague by using steeks (never done one, and would like to try someday), or converting patterns written flat to be in the round.
The LYS lady who taught me to do side seams didn’t use mattress stitch. She used a technique she had learned at a knitting workshop and liked better than mattress stitch. It served me well for a long time but lately I’ve switched to mattress stitch. It seems a little more exact.
I got to go to a finishing class last month and that was fun. I knew most of the stuff, but learned one new buttonhole and a new way to do shoulder seams that I have not seen anywhere else. It worked very slick, (and no it was not 3 needle bind off, the instructor was anti-3 needle bind off).
I try to tell myself to try to enjoy all the different parts of doing a project, but really I don’t 100%. I’ve noticed lately that I don’t relish projects that have a lot of fiddling around. I just made 2 pair of Doggie Booties (called slippers in the book) and I definately didn’t like having to attach all the little ears, eyes, tongues, tails and noses. It felt like I was doing a “craft”, and I don’t think I’m really a crafty person. I did it because I love the outcome, but the process? Not really.
