Ryan, the tarp is made by cutting a piece of tissue paper to the size you want. Then soak it in a 50/50 mix of white glue and water. drape it the way you want it to appear, let dry and paint. Properly painted it will have the appreance of canvas. Thx for the comments.
Great build up! I will say that these little dioramas are a fun and very entertaining challenge. Personally, I like, and appreciate, them more than the larger 1/24 dio's.
