Thanks ladies! first of all, I realized that I meant tea towels, not kitchen towels. Most of the kitchen towels I found were flour sack fabric. I had looked at All About Blanks and Discount embroidery blanks and wasn't sure if they had what I wanted. The ones at Discount Embroidery didn't mention that they were DBE, even though they came up in the search. The ones I ordered before were 100% cotton and some were hemstitched and cream, not white, so that definitely wasn't the same company.
HOWEVER, I did order some from Amazon that seem to be most like what I was looking for. They came today and I like them, except they only came in white. I think I have enough to start on Christmas gifts,
Thanks again for your suggestions.
