Here are some of my favorite places to shop:

Yarn: 

www.knitpicks.com  This site has wonderful lace weight yarn and sells dyes as well.  The prices are terrific.  Great quality.


Dyes:
www.wcushing.com   This is where I purchase my dyes.  They  have a huge selection of dyes.  They are easy to use and results are fantastic.  You cannot order from the website however.  Here is their toll free number:  1-800-626-7847.

Sewing Patterns:

www.adams-harris.com   Oriole has wonderful patterns for many modern dolls, including ball-jointed dolls.  Her designs are excellent and the fit cannot be beat.

Supplies:
www.tinyzippers.com  I buy my zippers and buttons here.
www.riorondo.com  This is where I get buckles for purses and shoes.
