I whipped up this cute little Iphone cardigan yesterday cause I wanted something fun to protect my phone with & I only used an old tee that was too small for me!
Once you have your two bottom pieces cut out, line up the seams from the shirt & lay them facing up. You will be working with your material inside out the whole time.
Sew your seams together
*Make sure you don't go all the way through the bottom material with your needle...if you do, the thread will be seen. This part of the shirt is thick enough that you can through one of the layers & it will hold strong.
