I purchased two of the same t-shirts on clearance last week to make this beauty. I have a good portion of the second t-shirt left and I have lots ideas so check back in to see what I come up with next.
1: Start with two t-shirts. You could easily use a different color or something you already have on hand. 2: Cut off the finished edge of one of the t-shirts. 3: Measure and cut a 6" strip. Then cut one side of the shirt so you have one long piece. 4: Make a running stitch down the center.
5: Now the fun part. Pull the thread to make your ruffle. 6: Adjust your gather to about 9" in length and pin on the uncut t-shirt right down the center. 7: Cut another strip about 2 1/2" wide by 12" long. Fold edges under and pin over center of ruffle. 8: Stitch ruffle on to t-shirt with a straight stitch.
