Here's an interesting development - The Modern Quilt Guild. To quote from the website:
"The Modern Quilt Guild is a community of quilt guilds across the country. The online community of modern quilters is thriving and this guild grew out of a desire to also have us meet in person. The founding branch of the guild started in Los Angeles in October of 2009. Through blogs & the internet word spread quickly of the fun they were having and now branches have started popping up all over the country. We are a young organization just getting started with planning, organizing and sorting out all we will do as an association."
Member guilds are linked on the site, and the modern quilt movement has spread to Australia and Canada. To learn more, visit The Modern Quilt Guild.
