I saw a show the other day from Sewing with Nancy where she was making Fabric tortilla warmers. I can't figure out how to make these and haven't found a good pattern on the internet. I tried looking on her site but it's a bit confusing. Did anyone see the show and/or does anyone know how to make these at all? I want to make one for my dad when he comes down next week because we always have a war about heating these things (friendly of course) and I want to end that... Thanks!
