I've got to admit, I'm a little sentimental about some of my earliest purchases. Buying supplies was a rare treat for me back then, so even though I've purged many things since, I still have some of my earliest supplies on my laptop HD.
From that old thread before the order history was wiped, I know my very first SSD purchase was 4/2/06.
I bought 2 Quarterly Assortments, Playful Plaques by Manda Bean, and Sweet Jane Stitches by Sandra Boddington
I used to break up the QAs by designer because they were unrelated mini kits, so I probably have some of those kits but I don't know which ones were in the QAs.
When the store reopened, I bought Atomic Bounce by Melissa, one of Traci's Bad Sewing Machine sets, and For All Occasions (card templates) by Darcy and Bree Clarkson.
I have some unused kits that I want to use and I shopped during iNSD, so I didn't buy a lot with my most recent round of SR. I got:
Erica's Stitching
and some of Cindy's templates
