In the Dollar General ad there were all kinds of picnic supplies - paper plates, Solo cups, and cutlery. This paper plate was perfect, with nothing else around it to obstruct the circle. I cut it out and added some nail polish to make it shiny. I then traced the circle onto an index card and cut out a bunch of tiny circles. I then bent them all around the edges with my fingers to give the effect of a lip on the plate. The dinner sized paper plate that I have at home measure 10 inches. This mini plate in 1:12 scale would be a 9 inch plate so it worked out pretty close.
I used a dot of glue between each circle in order to hold them all together and then I wrapped the entire bunch in saran wrap. The pictures look a little weird, but the paper plates look really cute in person.
This also gave me the idea of using my 1 inch circle hole punch to make some mini plates with cardstock. A 12 inch plate may be too wide to be realistic so I may have to look for a 3/4ths inch circle hole punch the next time I go to the craft shop.
