Bleach Bottle Hats

Today I saw a cowboy hat that was crocheted with the main part of the hat being plastic pieces, that seemed to be covered with material, crocheted together. The brim was all crochet. This perticular hat was done in red yarn, with the AR. Red Razorback Hog painted on the inserts. I know that several years ago there was a hat made somewhat in this manner using pieces of bleach bottle. I wondered if anyone had seen a cowboy hat like this and might know where I could get a pattern for making one.

this is the only one cowboy I could find
