Look in the sections where towels, wash cloths, dish towels etc are sold. U'll find them. they come in a fairly larg pack. *4U
Each Walmart is laid out some what differently but I'll give you a general idea of where to look. In the one I go to, there are several short isles set up together, the bathroom items take up two-three isles, the kitchen section is in the same general area and it has dish towels, oven mitts, place mats, etc. The bar mops are usually on a hanger in that section. The store I go to has some really nice micro fiber ones that I've embroidered and they turn out very nice. Since our store was recently remodeled they moved those items to the front of the store near the pharmacy, can't say that it is the same in the store you would go to. Good luck...hope you find them and you have time to make your gifts.
Thanks for all your help. I am on my way now to Wal-Mart. Will be back shortly with them to start sewing. Thanks again
