Hi Cathy! I used snap tape on these two... I have the pliers and snaps to do them individually, but they seem to pull of the fabric too often, and I didn't want to risk that happening when the babies needed to use them. The snap tape is kind of pricey, so I used a 50% off coupon at JoAnns. I was just about to look online for a better supplier.
The short rompers are fun too.
