We love stickers. We like to use them for all kinds of things. But, I've discovered, stickers can be expensive. Especially if you get elaborate ones at the craft store.
So I don't buy the fancy stickers. I go to the dollar store and buy circles, squares, and hole reinforcements.
I go to Walmart or other discount stores and buy stickers from the office supply area - circles, stars, rectangles - in all kinds of colors.
I sometimes go to the school supply store. But I buy the stickers that are simple shapes or letters - stickers that are smaller but come in packs with lots.
And the kids enjoy these stickers as much as any other ones I ever provide them.
I also notice that they make their own designs and creations. Simpler stickers encourage them to be creative.
And simpler stickers cost less - so I don't worry if they use lots and lots and lots.
