Do you have an old sewing machine? Or perhaps planning to buy the latest model?
Just a plain straight-sew sewing machine will suffice if you are starting a stuffed toy business. As they say, practice makes perfect; so don't be disappointed if you're not able to sew a straight line. Here's a tip: I've been sewing stuffed toys for so many years and I rarely encounter straight seams! Stuffed toys' fabric pieces are joined mostly along curved seams or darts!
So just relax and be comfy while sewing. Singer Philippines has lots of sewing machines you can choose from. Check www.singerphilippines.com and view their gallery.
