The sleeves need to be made first, so they can be sewn into the coat armhole before all the underarm seams get sewn. I cut out the sleeves, lining, and the fur cuffs, then basted on the trims, and basted the fur, then machine stitched everything. Now I'm doing the bead embellishments....
I stay away from the side seams because my sewing machine hates going over bumps.
I'll finish the ends near the seams after the sleeve seam is sewn.
