Wow! What an amazing technique. I needed all my powers of concentration during this class.
This is my experiment with just using the Blob brush to draw a pattern. I'm looking forward to trying the photo technique and pen tool images.
Here's a mandala pattern I made with some skeleton leaves that I had already vectorized. I think I am addicted.
Here's another couple using some pen tool vector artwork I had made for some colouring-in bookmarks. These mandalas are a LOT of fun!
This mandala uses another of my colouring-in bookmarks which I originally drew with the Blob brush.
