Diaper cover sets are becoming one of my favorite things to make for a couple of reasons.
#1 They're pretty quick, I can whip up a set in a couple of hours including sewing (which is the worst part of any crochet/knit project IMO)
#2 You don't get much cuter than a baby butt in a homemade diaper cover.
The first diaper cover set I made was for my Mickey Mouse Crochet Set (the patterns I used are included in that link- and yes- they're FREE!)
Since then I've made quite a few sets and this past weekend I finished some of my favorites yet. It goes to show that you can take the same pattern (in this case the diaper cover) and re-work it to suit whatever project you have in mind.
I tweaked the pattern slightly but I pretty much stayed true to the original. Adding embellishments is the quickest way to change up any pattern.
Here are some of the sets I've made recently: (some of these are for sale in my Etsy shop ^^)
