ARGH!!!

So I'm happily sewing along, enjoying my time alone. I finish the jacket bodice. I did the collare earlier, while I was waiting for my buttons to arrive. I take the collar out and get ready to attach it to the bodice. Then I notice that I sewed the collar bottom shut, including topstitching, instead of the top! I don't have any fabric left. I cut up the last of it for a pair of pants for Chungita. I suppose I could use the pants, but the grainline would be crosswise. I'm going to see what that looks like. Denim has such a defined grainline. Altho, it is likely that the only people who would notice are other sewists, and maybe not even them.
