Stickers - I file my stickers in this clear box from Ikea - only £1 for the box, and I made sections so I can locate the stickers I need quickly.
Ink pads - I'm starting to buy more of these as I've realised how much I love rubber stamping! I keep them in this cute tin that I got from Paperchase (it's supposed to be a lunch box).
Larger/small wood mounted rubber stamps - are kept in a tin too. I have four sets of tiny alphabet stamps that I got from a cheap £ shop (or dollar store to you in the USA!)
Clear stamps - it took me ages to work out how to store these little guys. I have so many now. I mounted them all onto card with double-sided tape, slid them into CD sleeves and filed them in another Ikea box.
Journaling cards - in a cheap basket found in another pound shop.
Washi tape is stored in another small cute tin... may have to rehome these guys soon!
Spare papers - another Ikea £1 box, filed by size and type.
