I want to make a cat toy filled with catnip for my kitty but my sewing machines is broken and I never learned to hand sew. What type of stitch or technique would be be the best to use?|||if i were u and didnt want any of the catnip falling out i would use the even back stitch or the over hand stitch either of those two would be best!!
