I make masks in three sizes: kid, tween, and adult. Here are the three sizes next to each other. Each mask is made of two layers of high quality quilting cotton with an opening at the top so you can add a filter if you want. My masks have ties for a secure and comfortable fit. The recommendation for little kids is 2+. Monitor children closely while wearing masks. Please send me a message and I'll show you which fabrics I have available for masks. I have everything from dancing unicorns to more tame options.
