Not sure if you have noticed or not - but I have been adding to my sidebar entitled "Favorite Web Stores". Not every sight is specific for sidesaddle, but I found each to be unique and very fun...although some are quite expensive. Still lots of fun to browse!
Here is a small sample of items:
A Ribbon Display Table
Sidesaddle motif napkins
Equestrian Book that I want!
Top Hat Charm
Custom Saddle cover! I have got to find a way to get one of these for my sidesaddle!
