The Paper Arts site talks about everything related to paper including stationery, scrapbooking, and DIY paper projects.

Continuing the Valentine’s theme, here’s another kit that the kids might like. It’s called Straight from the Heart: A Make-Your-Own Valentine Card Kit and features enough stickers and patterned paper to make 45+ valentine cards.

I think it also comes with a stencil as well as instructions and creative tips on how to make your cards special. The kit is a 32 page book and would be a fun paper arts activity for children - one that doesn’t involve the mess of paste or library glue!
