You can seam it up the sides or on the diagonal as I did. I like the diagonal because it makes it thicker where you grab the hot pot and it adds a little something to the plain potholder. It's made from cotton - best for the kitchen. You don't want potholders made from something that melts like rayon or poly!
Of course, I had to make something glassy to go with it: a cupcake button!
And naturally, I had to make a few more. In typical Holly fashion... they kept getting bigger! These should be up on the glass bead website later today.
