We are so fortunate in San Diego to have quite a few independent stores available. A few long time stores have closed in the past couple years such as Cool Scrapbooking Stuff, Cat's Craft Cupboard, Jazi's, GeGe's, Pink Pineapple and Yellow Bird so if you hear of any of these, don't try to find them, Here are some of my favorites:
thestampaddict.com » The Stamp Addict Blog
They have a large supply of stamps & many classes. If you are in town when Michael Strong is teaching with his line of stamps, I would highly recommend you try to get in a class. Here's some info on Mike: The Born Doodler is San Diego Rubber Stamping Artist Michael Strong
Paper Tales in Point Loma is a dream of a store& really nice people. Their classes run a little high for my budget, but you definitely need to take a tour of the store and bring lots of money - you will find so much you want.
Stamping Details : Rubber Stamps and Mixed Media in Poway / San Diego, CA
This is another dream store - incredible inventory. I am a little more old fashioned, so many of their classes aren't my style and some of their altered media art classes are outside my meager craft budget.
Debbie Design Delights: November 2013
I have not been to this shop since they moved, but she had the most amazing inventory in her old store. If you couldn't find something, no matter how obscure -Debbie had it in stock. Some of her inventory is older, but she has the newest stuff too. Debbie is an absolute joy & gives impromptu technique tutorials if you ask a question. Her store is just down the road from the Stamp Addict, so you can do both in an afternoon.
Of the Heart
This store is "close" to my heart as it is the store where I took my first classes & spent my first thousands of dollars when just getting into this hobby a very long time ago. They just celebrated their 22nd anniversary. Bev & Gretchen are wonderful - just so helpful & they taught me so much. They cram an awful lot of stuff in a tiny store. I also like their class prices - $15 each or you can buy a pass that gives you 4 classes for $40. They also have some free classes where you only pay for the supplies you pick out to use.
Hope that helps!
