Originally I had wanted forest green cushions for my new 13'
Scamp which I purchased new last summer. Unfortunately they had run out of that color. As it turns out I am now glad that we chose a greenish brown color "breen". While it looks "blah" on its own it is a great background color as you can accessorize with almost any other color.
I like to change up the look of my interior with curtain panels, pillows and throws as well as stuffed animals. I often match the interior theme on the exterior with tablecloths, salt and pepper shakers, and dishware.
Among my themes (all in progress) are South Pacific, 1950's, South of the Border, Red, White and Blue.
If you like to decorate you can have a ton of fun with some simple changes that don't cost a lot of money.
