Dale,
I'm fairly certain I'm going to be painting my lozenge again. I bought some color chips about ten years ago from a very good source that were matched to Methuen references on the lozenge, but since I had already painted the fabric for my version of Buchner's "lion", they went on the shelf. Now, I feel the need to use these references. I got them long before GTM started offering fabric.
I like Glenn's 4-color fabric, it has the right feel to it and the appearance is good. I know it's a bit tough to get nice and snug but the results are worth it. Lots and lots of dope. I guess the high shrink dope would be the nitrate first, and then butyrate. You can put butyrate over nitrate but not the other way around. I have three panels (two topside, one underside) that I was going to use on my E.V. Need some lozenge?
