I bought some 7gypsies stamps to use on an ATC swap, but when I got them according to the packaging I have to use them in a special stamping holder thingy 
has anyone got/used this, or can anyone suggest how I can use them without it? I'm not sure they'll stick on blocks unless I use tape or something.
TIA
