A couple weeks ago my neighbor dropped of a bag of clothes for me to look through that she is getting rid of. There was a loose sweater poncho in one of the bags. I liked the idea of the sweater, and items with loose, bat-wing sleeves are really popular right now... But this sweater was just a little too big with not enough shape.
My solution was to bring in the sides and make the poncho have actual sleeves instead of just arm holes. To do this I sewed a line of straight stitching where the new seam would be. Then I sewed a line of zig-zag stitch next to the straight seam. Once the zig-zag was in place I could cut the extra fabric away without unraveling anything.
I have worn it several times already, usually with a bright colored long sleeve shirt and jeans. This is becoming one of my new favorite sweaters!
