Popup Tent

trying to really "class-up 'my tent trailer with elegant fabrics and soothing colors. Can not take the high availability / extra fabric they seem to throw on all functional parts. Do you want to spruce everything within a budget. Already found GREAT fabric wholesale curtains to replace seat dinette / / and paint. Would like good suggestions. Thanks in advance!

You'll need a good introduction to your "plate".
Go to Home Depot and get the primer called "Gripper" by Glidden. The best! You are now ready to paint color you like.
Glidden and Benjamin Moore paint is high quality.

If you can sew a straight stitch, then you can make new curtains. Same goes with cushions. You can get yourself. Just use the old fabric for a base model.
Regarding the dinette seats - if they are attached to the chair, remove, replace them with new fabrics using a basic pistol and put on the rear seats.

You can do it yourself. You have the fabric, Now Get Busy! ?
