Ta Da! It's finally done. Last night I removed all the tape and finished the centers of the tulips. Today I looked at it and thought I could've done a better job on the tulip in the lower left corner so I retaped a few areas and applied another light wash. I got some very nice bleeds on the tulip and the background and thoroughly enjoyed this process. I would definitely try this again. It's a bit tedious applying the tape but more fun than a chore. Kudos to Sandy Maudlin for creating this technique.
