Craft Supplies Help!

Hi,
Recently, i have been seeing heaps of projects i like, but have only have like 1/3 of the things to make it with.
I am planning a craft supplies spree soon, but i need a basic overview of what the things i might need....

Here's some of the artcy stuff im into:

* Sewing ( basic stuff; purses, cases, bags, totes etc.)
* Popular projects ( basically all of the projects that you see in the most popular, i like)
* most of cat morely's projects
* simple organising projects

yep.....
Btw, any tips or help would be appreciated =*) Tanx
