I'm making the field trip top for a friend's son. He loves purple but his mom hasn't been able to find any non-girly purple shirts in the stores. I'm nervous about making something for someone whose not in my family and I really want to make sure that the seams are extra durable. I'm hoping he will love it and wear it lots.
I don't have a serger. I see the instructions call for a narrow zigzag. Would using a double needle make the seams even stronger? What type of thread would be best? Any other advice? thanks!
