A few weeks ago I posted about making a cloth diaper using the Rita's Rump Pocket pattern. I couldn't figure out how to put the elastic in, so I put the project on hold.
A fellow cloth diapering momma on BabyCenter posted a link to this tutorial. The directions are well-written and easy to understand as long as you look closely at the pictures. I love the idea of using a safety pin to pull the elastic through the casing; it makes it easy to guide it through, and tacking it down at the end is wonderful.
