First I cut the two main pieces and, using an awl, made holes for stitching. I proceeded with needle and thread and repeated the process on all five pieces.
Before I stitched the last piece on, I punched holes and fastened eyelets onto one of the sides (this so that I could check that the distance between it and the opposite lacing piece would be sufficient).
Then i stitched on the opposite lacing piece, did some adjustment cutting, stitched on the last bit that would protect the fingers, and (far too early in the morning) I was done! :)
