I would recommend that the tutu not be the tied on strips of tulle, but rather one continuous round like this: http://www.etsy.com/listing/85572599...facet=handmade
To purchase the Maraboo, Ribbon and Bows sells it as does The Ribbon Retreat. I would not recommend purchasing maraboo from Halo Heaven as it is not very good quality.
Best of luck! I hope you post pics so I can see what brilliant thing you come up with!!
