Mosaic Crochet “Me A Solid Heart” is an excellent sampler for those of you, who want to try mosaic for the first time. It’s 39 st’s wide and 27 rows. It measures approx 7 inches in height and 10 inches wide. This would be a great width for a scarf (39 st’s). Then you would just repeat the 27 rows over and over until you reach the scarf length required.
