I got to thinking that I was so preoccupied with finding brown beads that I hadn't really checked my stash for other colors. Yippee! I found a couple strands of aqua, a couple strands of teal, and even a couple strands of red! I was able to find strands of red, blue, and yellow at Picard Beads (thank you John and Ruth!). But if anyone sees any strands of brown for sale online, please let me know, I would be so grateful!
Again, so glad this group has been so helpful. 🤗
