I’m back with part two of sewing up the Sassy Sweatsuit by Patterns By Dee! A me-made sassy sweatsuit is perfect if you’re looking for a quick afternoon sewing project. I love a coordinating set, so I’m back to using the Minerva Fabrics Ponte Roma Double Stretch Knit in the print Melanated Marbling, a design that I personally drew for my Minerva fabric collaboration. I love how the set came out! I used my BERNINA 790 PRO to sew the sweatpants.
