I've made a couple of them as commissioned works. I did not use a stabilizer but perhaps the t- shirts in question were of higher quality fabrics. I know the owners and have asked how they held up. Things are good years later. Creating a pleasing layout is the biggest challenge. Measure the design areas first and see how many of them can match up either width or length-wise. THEN cut them. I am a graph paper fanatic. And it works for me. Good luck!
