Silk-screen a monogram onto leather for place mats. Use the same monogram as a pattern for matching napkins. You can embroider them (using colorfast thread) if you’re skilled with a needle, or send them out to a pro.
These labels are so cute, you may not want to hide them inside clothing. While the sew-on name tags and monograms are great for IDing kids’ stuff for school and camp, the badges can also add a graphic element to clothes and more.
