I made three t-shirts in size 16 (from the lower size range). I used three fabrics. The third t-shirt is made from scraps. I love the possibilities to mix and match fabrics.
I followed sew-along on True Bias’ blog and the sewing was smooth. The only problem was with the neckband. Kelli recommends one method for sewing machines and one for overlockers. I find the first sewing machine method more complicated. So I would use the second method for both machines.
The fit is not perfect. I would prefer wider shoulders and a bit more ease.
