Always test the tape and the iron temperature on a scrap of fabric first. Lift and lower the iron rather than sliding it along the seam. You'll see a narrow line of melted glue at the edge of the tape when it's adhered. Allow the work to cool before lifting it from the ironing board. Stitch and seal each seam before going on to the next.
Curves can be tricky to seal.
Clip the seam allowances before topstitching them in place. Support the curve on a dressmaker's ham while you press one edge of the tape at a time. The lining in a two-layer jacket needn't be complicated. Assemble the lining fronts, back, and sleeves with a serger or regular sewing machine, then place the lining unit wrong sides together with the assembled and sealed outer unit. When you add the collar, cuffs, hems, and drawstrings, treat the two layers as one.
