How do YOU stretch cross stitch pictures?

[summer-data]

Thanks so much for everyones replies, i haven't had the time to check in for a while but i really appreciate the detailed instructions. The company i've bought has used stapling for years with no customer complaints. I have a problem with potentially de-valuing and damaging work and the customers won't complain as they don't usually know until the piece is re-framed. It's my feeling that if someone had put so much work and traditional skill into a piece that i should strectch it in the same manner. I've been taught how to stretch with T pins and lacing and though it's more time consuming i feel happier with a more traditional method. So thanks again to everyone
