Rustic Outdoor Barn Wood Flower Wreath | Country Outdoor Wreath | Garden Lover Gift on Etsy, $29.00
Reclaimed Barn Wood and Vintage Salvaged Door Handle Towel Holder. I would think this would be so easy to make yourself! You could even get a pallet, cut it to desired size and stain to your desired color. Then find a nice rustic handle! I'm going to make 2 smaller ones for hand towels & a larger one for the bath towels.
