Newbie sewer seeks advice: I like to design and sew appliques on tshirts for my little boy. Its winter now though, and I was considering long sleeved tshirts. Then I had a thought - I recently got a used serger ( a 4/3/2) and was wondering what I would do with it - and I thought of a cool idea: I thought I could buy some coordinating stretch knits and attach long sleeve layers under the applique'd tshirts. But of course, I'm not quite sure how best to do this and its not something that sewing books have in it.
I assume I need to remove the hem in the sleeve, pin the new sleeve to it and then resew on the serger.
All recommendations welcome.
