Melons

Melons

I am very proud of myself, because I have grown melons in a mini greenhouse here in Scotland =) But I've never grown them before, and I don't know how to tell when they are fully grown, and ready to pick. :S What makes it worse is that I can't remember what the variety was called, and a huge snail has now eaten the seed packet!!! Can anyone advise?
Cool!
I only have five melons, so don't want to cut any too soon. But frost is also approaching in the next week or so, and I don't want to lose any by leaving them too long either. Thanks for any advice!!
