The nice thing about tillandsia, Cameron, is that the can grow in so many environments. They are not 'picky" plants. You don't need a lot of tillandsia or a large cork slab. I have single, small-growing tillandsia mounted on tiny pieces of cork (larger than a wine cork though) and single, large-growing ones on cork sized to their growing needs. Of course, my "Florida Natives" are on a really large slab, something like 18"x32". The smallest piece of cork is only 3"x4".
I think I still have a cork plaque made up of numerous wine corks glued to form a flat surface and then framed in wood, just like a picture would be framed. Though I don't use this for anything (but should), that's something that is easy to make and it can be sized whatever one wishes.
It is still dark out but when it lightens, and when I finish boxing up some plants for shipment, I will go out and take some photos.
