for lhaggard I have finished them different ways. Look at the pictures I posted of the tote bag. I did a yoyo for the center of one. On the grey tote I did a flat center with the grey material of the bag. See the ones Rhonda just posted..she put a selected piece of the material for the centers. So I guess you can do whatever you like.
for janice1120 I have used material with a 12" repeat
