I know about this one from April 28 - May 1. I think this is the same one:
http://www.quiltfest.com/activities.asp?id=35
At the Denver Merchandise Mart, as always.
Enjoy a unique collection of quilt and textile art from across the country, a juried and judged competition, fascinating workshops and lectures, plus the Merchants Mall offering everything the quilter, textile artist and home sewer need to fill up their stash shelves, finish that quilt and start the next masterpiece.
Workshops and lectures, full of fun and innovative techniques for beginners as well as for the more advanced textile artist will be offered during the Denver National Quilt Festival. Those interested in learning new skills, developing skills already acquired or just wanting to have some quilting fun can benefit from classes taught by an outstanding nationally known faculty.
