One little bit of extravagance that is a regular indulgence is a regular purchase of Moo cards. I love these business cards. They are delicious to handle - firm card with a matt plastic coating to give a soft satiny sheen. It looks very professional to have your own images of work on your cards and my quilts are often strongly coloured. I offer a fan of cards and suggest anyone who has asked for a card choose one. That offers just a bit of insight into the person who asked.
At different times I have used different types of images. For promoting my textile tours I have had cards printed with photographs from Egypt, Syria and India, and if I am doing a talk on textiles in Egypt - those are the cards I take to show off that tour.
I sprawled a few on my Syrian table cloth. They could be better photographs - but you will get the idea!
