Aashley 333, pins! No secret at all just pin and stitch. I even skipped a couple of steps on these, by sewing my zipper in between my front and lining all at the same time, repeating this also for the back and lining.
Thanks you two for looking again. I’m mopping this morning and while picking up things earlier, I found I could fit quite a few batting packages in this ex-large tote.
