|Wrap tops are so popular now but oh does that hem become thick (2 layers folded up = 4 layers). One tip I've learned in to handle this is press up the hems, pin layers together, then cut away the inner layer. This reduces the thickness to 3 layers, which makes a great difference. You may need to baste or pin the bottom cut edge on the inner layer in place til you hem if it wants to creep up. See photo.
