Emblibray has some really cute 50-60 designs. I just got the hamburger boy and the one with the cup on his head. There are also some of the retro appliances. Check it out. Not free but there prices are good and I usually have a discount coupon. Carol

some diner designs here. reasonable prices

If you have Google or some other search on your computer ~ type in retro dinner. There will be more inspiration and pictures to view. Will be waiting to see the finished camper. Have fun with your project.

there is a "juke" box music selection radio (not a design) you've got to have for a diner look. I'll try to find the link.Don't forget 45's around the walls. Pictures of Elvis, pink poodle skirts, saddle shoes,pictures of Hot Rods, old Pick-ups.Green malt machine(gotta have this) and 5 cent bottle coke on the counter, next to straw holders.

This sounds like fun. I am thinking red checkered fabric. Definitely towels with vintage designs. oilclothflannel tablecloth. Well, my memories of kitchens and diners is empty now. Do we get to see a picture of the finished trailer?

Sounds like a fun project you can really sink your teeth into. Sew Weird has a lot of vintage designs. 1.This link takes you to one page, scroll down to the bottom and go to the home page for more.

Lee,
I think www.juliasneedledesigns.com has some of the 50's and 60's era designs on her site.

The red checkered table cloth with matching curtains would look great. Carhops, jukeboxes, and classic autos
on throw pillows for the sofa/bed would fit.

Bet you decorate it great!
