I just finished an Aran sweater for my sister-in-law. It was worked from the top down with set in sleeves that were worked along with the body because I don’t like sewing seams, especially fitted sleeves. I was completely winging it while deciding where and how to do the increases. Here is a close up of the sleeves in progress:
Here is the finished sweater. It is my own design, but not very original.
So very beautiful and so intricate. Your knitting is superb. I hope your SIL knows alol the work that you put into this sweater and shows her appreciation by wearing it, LOTS!
