Sometimes it helps to see sewing tools in their packages so you know what to look for when you're at the store. Those amazing turing tools look like this and I found them near the grommet/snap gadgets.
Now, on to elastic thread. It's all the rage in the blog world. I made a dress using it and wanted to do more things because it was super easy, but thought it was a little pricey (the dress took almost the whole spool). The first time I bought it, I looked in the thread section and found the Gutermann elastic thread - only 11 yards and around $3 (pictured, it's the yellow spool). Killing time at the fabric store while waiting for my turn to get my fabric cut, I happen across a different version from Dritz back by the elastic. It comes in a package as pictured - and has 30 yards for only $1.50. No wonder everyone is using elastic thread - I wish I would have bought this stuff the first time!
