Training pants

Ok, I have to type quick because my baby daddy is trippin'. I keep telling him over and over again you can't "babysit" your own child, its called parenting... Anyways, I wanted to quickly go over my latest project: training pants for Manny. He is now 8 months old and pooping almost exclusively in the pot, however I miss a lot of pees, so I would like some trainer pants that pull up and down. I just got some organic bamboo velour and fleece and I already have some wool interlock, so I'm thinking about how I can combine them to create something like this http://doityourselfec.blogspot.com/2008/01/wool-in-two-training-pants.html.
