I agree with Ryan (I usually do...), although you'd probably get away with two and four from the left.

To answer your question about how many stamps you need, you need to check the weight and size of the envelope you're expecting to come back on the USPS website - that part of the question has been answered so many times on the Collecting Help forum that you won't have any difficulty finding it.

Good luck

Personally I wouldn't use those again as they look used and I'm pretty sure if you tried they'd probably send it back to you RTS. or send you a letter about how reusing stamps (even if they aren't cancelled) is against the law and could result in some big fines. :neutral:
