Hi LaQuita, welcome to the group!
Like Mirabelle said, the 6 " Sylvia blocks are very manageable, they're mostly regular blocks. The book provides directions and templates.
The DJ blocks are different ,no directions or templates, no regular blocks and they're 4.5" finished. Lots of tiny applique pieces.
Some use scraps as background and some have the same background. It's up to you what you want and what you have.
