My former store, Scrapbook-Elements.com has a huge list of tutorials for PSE.
Another huge list of tutorials is available from Designer Digitals
Digital Scrapbook Place also has very good PSE tutorials.
Scrap Girls is a great resource for ebooks and tutorials.
Hummie's World also has some great links for PSE users.
I hope you find some of these links helpful. Please let me know if you did.
Have a great weekend!
