If horn bands, very few. Finding a horn large enough to supply bands is the problem. Your wood idea will solve that problem. I picked up two of the same breed of cattle at CLA 3-4 years ago. One was made a simple horn for local club to use for listing member’s names. The second horn I’ve done for them in the last 20 years. The remaining horn I trimmed and only have a 4 1/2” plug to fill. Will wait to see how your wood bands work before I finish it. Looking forward to it.
