WOW!!! this quilt is fabulous & unusual. i've never seen this pattern in any of my books of vintage quilts. if it were mine, i'd send a pic & the story to barbara brackman & see if she has any info on this pattern. on her website she frequently shares pics & whatever info she can find on questions people write her about thier finds. and your repair work is wonderful!
