If you're on Facebook, contact Sherry from Irish Quilting. She also just had an article in the Quilt Life mag. She is fantastic at promoting her country.
I'm in Ireland in June too, Mayo though, and I have my little list from Sherry! One thing she did tell me was that a lot of the 'shops' are cottage inhdustries and are from home so sometime a call first is a good idea.
I hope you have a great holiday, Ireland is wonderful (take waterproofs!), and the scenery around Kerry is fabulous!!
