I had used Papermania rub ons once before and had the same problem, but that time I wrote to DoCrafts asking for an explanation - why weren't there rub ons rubbing on and what can I do about it?!? Apparently, there were some faulty batches that slipped through their quality testing. They sent me loads of freebie goodies to apologise, which was lovely, however, that doesn't help that loads of craft shops/sites with old PM stock are stiill selling these defective rub ons - and you don't know until you get them home!
Anyway, rant over and back to the card...the stamp was a PM ornate stamp that I used a decoupage effect with by stamping it several times and cutting out and layering to highlight the shapes in the stamp. I then used a felt tip (!) to colour various parts in and glue and glitter to glitter the detail. I love the rich effect this gives and it suited the bride and groom in question down to a T!
