I've sewn in the sleeves. So I'm almost at the finish line – but I thought I'd just get some final input before I do anything which I don't want to reverse! As you can see, I *was* going to lengthen the back hem, but I'm not sure. Depending on how upright I'm standing at any particular moment, it seems slightly too short or about right. Should I err on the side of "too long or about right", and lengthen? The other thing is that the sleeve heads seem to be coming out too far, so I get an indent. Can correct this? Do I just need to press it in a particular way, or take out some wadding, or is it a problem with the sleeve itself? Thanks!
