I have just this very minute finished ironing some prefolds that I have made for friends who are expecting.
I've never used them, nor seen one in person, so after googling and examining a bunch of different tutorials I dove in.
I pulled out some of the flannel sitting around in my stash, which just happened to be pink and yellow (that being what was on sale). Found some REALLY cute cotton print that matched the colours. Pulled out some old towels donated to me by my MIL, and acquired a couple of microfiber car towels (that 'pull' the moisture away) for the padded panel.
Baby-To-Be has no determined gender, so hopefully I won't get too much guff about the pink if it ends up threatening to shrivel baby's penis by its abstract femininity or somesuch.
I have no idea if what I've ended up with are newborn or toddler size, I cannot draw a straight line to save my life, and that has sadly translated into sewing. So they're somewhat wonky (for that authentic "handmade!" look), very adorable and delicious, my first prefolds!
Now to find some instructions on how to fold them, to include a printout of for the Parents-To-Be.
