I just measured around cup and folded material in half top to bottom.. Placed some insulation for hot pads inside. Stitched up and closed with velcro. It was funny because I sent daughter a picture of it and she in turn sent a link to Etsy where woman was selling these on pop cans. Thank you all. Susan
Can you post the blog post of where you got the tutorial? My computer was really slow so, I didn't get it saved. Thanks.
