I just tried TPU clear vinyl for the first time yesterday and it was bunching up on the underside so bad. I'm wondering if that's what was happening to you to? I will definitely try this type of thread. Thank you.
Just curious if changing your thread allows you to sew 2 pieces of the clear TPU together or if your machine will only allow you to sew a layer of jelly and a layer of TPU together? (I like how your videos show you using it that way because mine will sew that, just not 2 layers of the TPU vinyl!) I have a Brother. Do you mind sharing what you sew on also?@@justynathandmade
