Step 2: Cut out your pattern in the new fabric. For the sleeve I used a cotton waffle weave. Sew the sleeves to the body.Step 3: Right sides facing, sew up the inside seams.
Step 4: Now for the neckline... Here's the formula, you'll need to measure the neck, mine was 23"
23"(Neck Measurement) - 15% + .5(seam allowance) = neck band length
Step 5: Cut out your neck band. I went on the bias, two inches wide.
Step 6: Right sides facing, stitch ends closed. Fold in half, turn right side out.
Step 7: Pin and stitch to the shirt, raw edges together. I used a stretch zig zag stitch.
