I have always loved doing patterns, starting with the fabric in the ladies clothes when i was doing all the falling ladies...
Then there was the patterns in circles in my mandalas,
Now to turn those same patterns into repeating patterns is so much fun....
And i have gone to index cards and pens instead of my watercolors, just temporarily, because to make the repeating patterns i cut the cards in quarters or use two or even four taped together. And i don't want to cut up my sketchbook, but i have no problem cutting index cards.
Plus i love the colors in my set of pens, bright but juicy looking,
like fruit flavors....
