Thanks for the link, I wanted to let you know that I sew stuffies too. I use upholstery thread because it's very tough, I've never had a repair come apart. They just find a new way to destroy the toy! I spoil my boys too, but most of my money goes to vet bills. Seriously like $5k in the last few months.
While I haven't spent quite that much I know what it's like to be hit with heavy vet bills. I got my pup from animal control. She had kennel cough, an ear infection, worms, and fleas. Along with that she needed to be spayed and given all her shots. Great idea with the upholstery thread, I'll have to give that a try!
