My own addiction is stamping, and I  have a large selection of stamps and stamp sets, including Crafty Individuals, Personal Impression, Hobby Art, Woodware and Creative Expressions.  Also,  ink pads, distress inkpads, embossing powders, cosmic shimmer paints, powders and sprays,  promarkers, water colour pencils,  punches, alcohol inks, brayers, decoupage including Dufex, as well as the basics like card and scrapbooking papers, blank cards and envelopes, foam pads and double-sided tape, heat guns and paper cutters.    

Although I do not have an online shop, if you know exactly what you want I will always send it to you.  

Most important, I am always happy to advise on 'how to do it' and have fact sheets available for many techniques, or why not book a class.
