I have a good yahoo friend in Dublin, Ireland. We are both members of a fibre group called Art4Mail. Miriam is the president of the Irish Patchwork Society, and she has told me about the society's 30th anniversery this year. To celebrate, they are running a postcard exhibition - it will be on display in the Botanical Garden in Dublin in August. They want both national and international entries, so these are the two postcards I've sent them. Postcards will not be returned, but sold in aid of an Irish Breast Cancer Charity. The deadline for entries is mid June.
If you want to send a postcard, you'll find all the details - theme, address and so on - here. The first card is pansies from my garden, trapped under organza. The second one is silk fibres felted on wool, and with some hand embroidery.
