I think my Polaroid notebook idea is a great one, if I say so myself (using a Polaroid from my Polaroid subscription and these tapes.)
A glassine envelope wrapped with these tapes. There are so many craft opportunities (if you are into that kind of thing) as it's low-tack, tears easily and can even be written on. I've had wallpaper samples stuck on the wall for over a year with this, and it still doesn't remove the paint when you take it off. Here are some brilliant ideas I've seen - I'd love to hear your suggestions.
More lovely invitations using the same bunting idea.
And this is my favourite - using a stamp to customise the tape. Skull and Cross Buns on Folksy has a range of rubber stamps.
To celebrate their arrival (there are more coming soon), I'm offering 10% off everything for two days if you use the code teaforjoy (finishing Wednesday.) My favourite new items are these striped notebooks (with the text 'Writing, drawing. A notebook makes me feel free and happy' - sometimes Japanese items have quite random English sayings...)
