Here is my center block for the Cyberbees 2012 RR.  The fabric with the pots will be the backing.  My center is 14" x 16". Yours can be larger or smaller, although 12" is usually what I've seen as the start size.  For of those of you who prefer to embroider, that is a possibility, as applique or pieced blocks look nice with embroidery also.  If you stroll through this blog you will see the 'lost'  RR. center that Tisha began in redwork.  Hope at least 4 or 5 cyberbees will join in. Please let me know on the list. Thanks for considering this , Tam.
