Is the Inside of the Casita
sort of a "Robin's Egg Blue"? Ironic as you now have "Robin's Blue Egg"!
When I was looking for an egg camper
I saw one with a Blue Shag Interior and one with a Burnt Orange Interior. Since I was so desparate to get an "Egg" (any egg) I even considered ways to make it work-I had a whole theme going that incorporated the strange colors (sort of a jungle/tiger theme for the orange and an ocean theme for the blue)-but then the sny-pers got them away from me at the last minute on E-Bay! That's fine now that I finally got some "glass" last week when I picked up my camper in Arizona-YAY!
This is probably a long shot, but some carpet cleaning products seem to fade the carpet a little bit. Maybe if you use one of those steam cleaners on it (with a cleaning product containing a little bleach) the blue color will lighten up and seem less noticable?
You can also probably attach velcro (the hook type) to the back of some sort of fabric (I'm thinking a cool Hand-Dyed sarong or light
quilt or batik type of flag) and cover the large swatches of blue with something you can stand until the rally
in Oregon, when you get some good ideas for getting rid of the blue shag.
I'm going to go look and see if I saved some pictures of the blue shag Casita
from E-Bay. The owners had it done up nicely with some yellow accents.
