Macy, you can do either. I have seen one bigger item in the center (fussy cut) and a few smaller items scattered in the square.
I look at I-spy fabrics like this: If I were sitting down with a small child, and I wanted them to "find" something, would they be able to figure out what that something was by looking at the fabric I chose. I have gone so far as to take a 5" square along with me to the fabric store to place on the fabric so I could actually tell what they'd see once I have it sewn in the quilt. It helps, but I'm a visual learner that way.
Does that help?
I've had a question about making the baggies bags of 15 instead of the ten rbwiese typically chose. I think bags of ten will be okay, particularly since we increased the number of bags to be limited up to 15 from our normal 10.
Am I thinking of that correctly, or does everyone think we should change the baggie supply to 15 from 10?
