No matter the pattern, I always change it straight out of the envelope. Here I alter a Christine Jonson pattern, #1025, Base Wear Two. I like this pattern a lot. I also find Sandra Betzina, Burda (and of course, Marcy and Katherine Tilton) patters run true to body measurements. The changes I demonstrate in these videos will help you customize any T-shirt pattern to your own dimensions.
