Are you going to make the Dresden plate petals all different colours? Are you going to appliqué the plate to a background fabric
or do just plates? Is the table runner going to be 2 solid pieces of fabric, front and back or are you going to add Dresden plates to the ends? Inquiring minds need to know a little more details.
I have a pattern for 4-141/2 Dresden plates and a 15X43 tablerunner and 4 napkins. Adding up the amounts are about 8 fat quarters(4 of those for napkins) 4 and 1/2 yards of main fabric.
