StyleDollz is pretty good. I'm not a huge fan of their bases though. For that,
I go to Dolls.Com.Br
(beware, the site is in Portuguese. However, if you type the site address into Google, it will give you the option to translate the page.)
They have great stuff and decent tutorials.
Typically, I customize and or create all of my dolls on MSPaint. Tedious, I know. It just gives me the freedom to get it the way I want things. I spend about 2-5 hours on 1 single doll.
As far as glitters are concerned, you can definitely have a glitter doll without a premi account. After making my dolls on MSPaint, I save them as a PNG Image and upload them to Free Online Image Editor
It's a pretty decent site that lets you add flare to your dolls. Voila- Glitter without the price of the account.
