Do you hate making elastic casings, or is that just me? Instead, I've been making bloomers out of jersey fabric and shirring the waist and leg openings with elastic thread.
I use Dana's Perfect Diaper Cover pattern to cut the fabric (old t-shirts work great for this). Before sewing the front and back pieces together, I sew two lines of elastic thread on the leg and three rows to the waist. Then sew together at the sides and crotch and they are done, lickety-split. You don't even have to fold over the seams on the openings, because jersey won't fray. They take literally 10 minutes to make. As a bonus, they are super stretchy, so I think they'll fit a long time. Hurray for that.
That's all for today. Hope you're having a great week!
