I completed by moto jacket a few weeks ago bar the snaps, two on either side. Being a bit nervous because it was the first time I'd done them I had waited until all my ducks were in a row and DH out of the way (he tries and helps and I wanted to do it myself). Main worry was the fabric where the snaps were had some decent interfacing and fabric a good weight, so I knew that might be a problem.
Anyway the sample was fine but needed some hard knocking. Got the first side on top done, getting anxious because it really did need brute force. Perfect, feeling much better I did the second hole, perfect. Just ready to put the top snap on I dropped the top one onto the floor, picked it up and stared a bit more closely at my hole. I'd put the hole on the flaming collar . A bit of swearing, not much considering, I went through my options. First thought, take the top side of the collar off, replace and stitch the back hole up. Went down to make a cup of coffee and had a rethink. All the jackets I've seen recently have two snaps each side, collar and the facing piece. So gone with another one on the collar, which didn't take as much hammering.
I'm relieved but left it for another day for the bottom snaps. I hate doing stuff when I've been flustered. The tool I got with the first set of snaps has split open on one side, which is just as well I got one of the pyramid tools and the plier set (that made a lovely hole with no messing).
