I just started sewing my first diaper cover. I ordered celedon and deep plum merino wool from fabric.com. It's very nice and it came so fast!
I'm following advice from
this site. I downloaded the free German diaper cover pattern, and went to sewdiapers.com and followed her direction for making jersey diaper covers.
To felt the fabric, I washed the celedon wool on hot, dried it on hot, then washed it on hot again with a little eucalan and dried it again. It isn't that much thicker or tighter than the wool I haven't washed yet, but I think it shrank a bit and it's a little fuzzier.
Oh, and I added 1/4 inch seam allowances when I cut out the German pattern. It looks like they serged around the edges of theirs, and I'm sewing the 2 layers right sides together and then turning it, so I thought I'd need the extra allowance. It seems pretty big, but I haven't turned it right side out or put the elastic in the back and legs yet.
warneral - what color are you going to dye? I like the idea of using foldover elastic. This merino wool is very soft, but it seems like elastic binding would be a little smoother hugging the skin. I've never used that before. Can you dye that too, or will it contrast?
