Final product Step 1: Get old onesie and pair of scissors. I already made a mistake on Step 1 when I chose a onesie with fabric that stretched too much. Step 2: Cut off the bottom part of the onesie if you want it to turn into a tee. I did that because this onese is now to small for Brie. Step 3: Cut lines across the back of the onesie like shown above. Step 4: Stretch the "strips" of cloth that you cut. Step 5: Loop! Loop the first strip below the second strip. Then loop the second strip below the third... Until you're all done. Step 6: Cut the last strip in the middle. Step 7: Use the cut/last strip to knot the end of the loop. This is also a good time to fix the loops so they look better. Step 8: Cut the sleeves. Step 9: Cut off 2 strips from discarded parts of the onesie. Step 10: Use a strip from Step 9 to tie the sleeves. This is part of Step 10. This is also part of Step 10.
