In my ATCFUN group I joined a mingle where we start with a 6X6 piece of corrugated cardboard. It actually turned out pretty well. The scan didn't turn out very well so I used my phone. It isn't great but it's a lot better than the scan.
It all started with a leaf. You know those dried up skeleton leaves that come in a package? You used to could get them. I've had these a long time so I'm not sure they still sell them. Just looking at them gave me several possible ways to use them. I finally settled on one. Although it changed several times along the way.
Hope you are having a Happy Day!
