Cork boards, cork blocks, etc can be found for little money and will provide both information and artwork display space. Woven sisal rugs can be used similarly. A quilt hung as John suggests will act similarly, and could also be backed with lightweight, preferably fire resistant blankets or denim insulation batts (class 1 fire rating) - just pin/baste them together before hanging.

A few pillows in appealing colors will help as well as enhance comfort and appeal (large used polarfleece-type pullovers can be altered to make fine covers that are also soft and friendly... and washable.) Cork also very fire resistant) panels may be helpful to mount on the inside of your door.

There are those of us who would be delighted to lend a hand once you decide what you need.
