Teddy Talk: Creating, Collecting, Connecting

Hello hello
I am so excited to be writing in here. Im still relatively new to teddy making. But already hooked.

I have been making teddies and recently Ive been adding foot pads but im noticing them tearing at the seams. I have tried using fur and also some with felt but they are tearing and showing stitches to the point its not very cute. Is there a certain type of fabric i can use? Or is it my stitching? Ive been hand stitching the foot pads to the legs as they are so small.

Also Ive noticed my fabric tearing at the seams in other places. Should i be adding some sort of interfacing to my fur fabrics so it doesn't pull away leaving holes when I stuff them?

Thanks so much!
Talia
