Way back in 1977 I went to the First Continental Quilting Congress in Virginia and what a show of quilts that was!! I saw Jinny Beyer's quilt "Ray of Light" which won first prize in the Good Housekeeping contest. But, back on the subject at hand...there was also a gorgeous christening quilt which had 6" round doilies appliqued on a royal blue velvet background. I don't crochet but I thought it was such a unique way to combine the two art forms. I should think that if you were to use the finer weight of thread it would work just fine. I don't think it would be practical for an everyday quilt but what an heirloom it would make!!
