A few choices in different materials:
I found a lovely metal stencil I am thinking about myself to use with pastes
Hot Air Balloon Metal Stencil
I am having trouble locking down a search for plastic stencil bc it is giving me wall stencils etc. Maybe someone else can do better-I am sure they are out there.
I am not sure what this is....lately we are seeing EFs that also cut out bits...if this is that with the balloon I really like it for shakers. Maybe someone else has it and can tell us if it cuts the balloon or it has to be hand cut? This is the lowest I found it for so far
Sizzix Impresslits Embossing Folder - Hot Air Balloon 662830 - 123Stitch.com
here is a better choice for a graphic 45 page cuz you can get just the one sheet
Graphic 45 Imagine Up and Away Paper
this paper is good for a BG vs a focal point (there are others too)
Simple Stories Simple Vintage Traveler Enjoy the View Paper
obviously these are my taste; there are others in different styles I like too but dont want to do a whole page of them
If you like stickers/have kids this set is larger than the Jolees and cheaper
Sticker King Stickers-Hot Air Balloons
If one googles washi tape there a lot of pretty ones.
