Sew U Home Stretch: The Built by Wendy Guide to Sewing Knit Fabrics. The neckline stretched by four inches when I applied the elastic, making me look like I was wearing a wavy bag around my neck. Forty-five minutes of picking out serger stitches was well rewarded with this improved version. I switched from standard 1/4 inch knit elastic to 3/8 inch clear elastic, set the differential to 2.0, and stretched the elastic as I serged. Yes, that was overkill. But the new neckline is cute. And I can wear it while biking without flashing oncoming traffic.
Another challenge was choosing an applique to cover up the advertising text under the tigers. My husband, who donated the shirt I cut up for the project, suggested the bow tie. I like the randomness of it.
