I don't know why the last updates for some of the other blogs listed on the right side of the page aren't updating (for example, it shows the last update from A Suitable Wardrobe being two months ago, when it was really yesterday). I've triple-checked all of the links and they're all correct, so I don't know what else to do; hopefully it'll resolve itself eventually. It's frustrating, especially since the truth is I started this blog in part just so that I could have a list of all of my favorite blogs in one place, along with the dates of their last updates.
The heat "sealing" method to prevent fraying proved to be inadequate.
So I bought a product from Singer called "Fray No More" at Wal-Mart for $4.00. (The only way to buy it was in a twin-pack with another product called "Sew No More," which apparently is some kind of adhesive thread replacement. I have no desire to try it.)
It's a little bottle of clear liquid with a pointed applicator tip, like a bottle of Elmer's glue. I fortunately had saved the scrap pieces of bands, so I tried it on one first to see if it would stain. It didn't, so I forged ahead with all five bands. Just release the clear gel onto any cut edges and let dry for about 30 minutes. So far, so good.
