I happen to have these photo on my iPhone so i though I could share it with you all :) this is how I store my thickers . It's a plastic basket from Popular bookstore ( it's a bookstore in Singapore) and it fits the 6 inches thickers just right . At the side I can also put in 12x12 alpha stickers from prima and Lilybee :)
I sort them by type - fabric / foam / puffy / chipboard etc :) Amy tangerine 's thickers have it's own section! Probably cos I collected too much of them haha .
This work well for me so far . Like shimelle says , it depends on what system works best for you. I happen to be the kind of person who look for the designs / texture rather than colour first . After I have the design right then I will look for the right colour :)
Thanks for looking !:)
