I digitized these myself! I found an outline of a onesie and old-fashioned diaper online, brought it into Embird, and made a redwork outline. I made a single stitch "pocket" for a tiny candy to slide in, too.
These are stitched on felt, but I added a layer of fabric on top for the onesies, so they would have cute prints. The outline is stitched on the top layer only, then the back is added to stitch the candy pocket.
Not only were these a decoration, but we hid a sticker on one of the candies. At the end of the party, everyone chose one and the one with the sticker chose a prize! These were very quick to stitch and made a great decoration. I might try these with different themes (if I have time)- how cute would a garland of pumpkins for Halloween be? Or a garland of angels or trees for Christmas? I may put these for sale in my etsy shop- would there be any interest?
