I sold my last batch of these vintage May baskets a little while ago and decided they were too cute to send off without at least scanning in.
The originals were perforated for easy punch out and assembly, but you could easily replicate the effect on your own.
If you click on the file it will enlarge and you can see the cut and score marks. The originals are just a plain 8.5"x11" piece of cardstock. I thought about enhancing the colors on these before posting, but settled on the originals for their charm and nod to yesteryear.
