I made this almost a year ago... Started a new one today and thought maybe I could inspire someone else to reuse old t-shirts or jersey to make something awesome!
I'm using a latch hook canvas for the new one but I'm regretting not just sewing it. Sewing is much faster. Just sketch out your design and stitch many 1"x 4" strips in rows. Starting on the inside and working your way out is best so it doesn't get too bulky.
