Karla, I use tags that I made on the computer with all the info and prices on them and I use a small safety pin to put on the items. I've tried sticky price tags and they don't work. They end up falling off and sticking to other things....it was always a mess.
I did find that it was important to have everything priced in case you are helping someone else and can't answer another customer on how much it is. I know when I go to a store and there is no price on something, it makes me frustrated and I just put it back.
I also use baskets for my sets of coasters and potholders and put signs on them. Hope this helps. I hope all goes well and feel free to ask anything else!!!
