Main Street Quilt and Thread Guild will celebrate 20 years of nonprofit service in July. The group was founded in 1999 to foster an appreciation for quilting and to educate the public about the history and preservation of fiber arts. Membership is open to the public and to quilters of all skill levels. Main Street Quilt and Thread Guild meets at the Round Rock Public Library, 216 E. Main St., Round Rock, on the fourth Tuesday of the month except in November and December. www.mainstreetquiltguild.com
