RBD Challenge block #4

This week's Riley Blake Designs block is Tulip, by Jill Finley.  This challenge has a new block posted each Tuesday, except the last one of the month. So it should be a pretty easy challenge to keep up with.   

The blocks are 10" finished.  And I'm using all blues from my stash.  The background is a small blue dot that was hiding in my stash probably for a long time.
