Here is a mandala I made using differently colored paper circles that I embellished. I have included a few photos of the process as well. It is quite simple and very rewarding.
I have an old paper cutting system from Creative Memories that is very helpful in cutting the circles in graduated sizes. In the photo on the right you can see how I line up the circles with the grid on the cutting mat to help make the marks symmetrical. I also trace each circle on the one below as a guide.
Happy Holidays and I hope you have a beautiful day.
