We use prefolds and covers almost exclusively on our little ones. For us, it's the easiest and most economical diapering choice. However, when I was building up our stash in preparation for Oliver's arrival, I found myself a little uninspired by the plain white prefolds. Why should fitteds and AIOs have all the fun? So, I set out and dyed a whole rainbow of colors!
I was a little apprehensive at first, as I imagined it would be super-complicated. But it really wasn't too bad! I used Dylon Cold Water Dye, purchased at Joanns. Each packet can dye 8oz of dry fabric, or about 3 infant/medium prefolds. You can do more but the colors will lighter and less vibrant. (Another fun option is to toss a couple white onesies or t-shirts in with diapers. They don't take a lot of dye, yet make a cute ensemble.)
To begin, you'll need to set aside an afternoon for this project, preferably when your little ones are taking a nap. If using new prefolds, be sure to wash them several times to prep them. In addition to the diapers and dye, you'll also need 4 tablespoons of table salt per dye packet. As far as where to dye them, I just used our kitchen sink. Even after multiple dyeing projects, I have yet to have any discoloration. (You'll note that I'm using a plastic dishpan, but that's only because I accidentally tossed away the sink stopper for that side and keep forgetting to get a new one).
After the first 10 minutes, occasionally give the diapers a swirl, pushing what's floating on top back under the water. The packet says to dye for a total of 1 hour, but there's not harm in letting them set longer for really vivid colors.
Run the diapers through a hot wash cycle with usual detergent. I did this twice to ensure all the excess dye was removed. I haven't had any problems with the diapers bleeding, even when they are wet and tossed in the diaper pail with other diapers. However, be sure to take care the first couple times you wash them just in case.
I'm thinking about adding custom dyed and embellished prefolds in my Etsy shop, for those who don't want to fool with the above. But I definitely recommend you give it a try! Although, I must warn you... you might get addicted as I have! :)
If you've dyed diapers and blogged about it, please post a link in comments. I would love to see them!
