Recently, I found out that there is elastic thread that you can use in your sewing machine to create a shirring effect. The best tutorial I found was here.
I went on the hunt to my local JoAnn Fabrics store but they only had one spool of black. I was told that once the last one was purchased, it would trip the system to order more. And, it could be in sometime within two to three weeks. Whaaaat? So, I went to Walmart (shh, don't tell, I really don't like them) and went to the fabric section. And found some in white - and they were only 88 cents, which was cheaper than JAs, so I bought all five (or was it six).
Today, I had a little bit of a chance to play around on a scrap piece of fabric, and let me tell you, this is going to be so much fun!
