Hello and welcome,
I am really taken with one of the products from the Spring Summer catalogue - the mini treat bag framelit. It makes a little treat bag which you cut and stick together. So far I have tried this with Stampin' Up cardstock, vellum and dsp and all work really well and are so cute.
I decided it would be a perfect envelope for a card and it just so happens the Valentine's card I have made my hubby fits in it!
The stamps used are the "You plus me" set which coordinates well with the hearts embossing folder and "Stacked with love" mini dsp papers - 48 sheets of double sided paper. At 6.5x4.5" they make a great size for cards and 3d projects and, of course, fit fabulously on a mini treat bag.
If you are interested in browsing any of the catalogues to find out more about any of these products or how to earn free products until the end of March, please do not hesitate to contact me at firstname.lastname@example.org
