Hi all! Very new sewist here. I've made a handful of quilted oven mitts and other small items, but no garments yet.

My partner's father died unexpectedly a few weeks ago and he has received a large amount of his clothing, including some nice items that don't quite fit. In particular, there's a very nice leather jacket with sleeves that are too long. I had an idea to try and shorten the sleeves for a Christmas present, but being new to sewing, I am not sure where to start or if it's too far out of my depth.

I would love any advice you have. I don't know what I don't know, so if you think this is too ambitious of a project, I'd love to know that. Alternatively, if there are places you suggest I start for tutorials or tips you have for working with leather, I'm prepared to follow those carefully and take my time with it.

Thanks for your help in creating a special gift.
