I'm doing a GFG in blue and yellow with 3/4" hexagons for the guest bedroom at our cottage. I agree that it is very relaxing. I print my hexagons on card stock and cut them out. I can use the same one several times-the card stock holds up well.
I have no idea exactly how I'll lay it out though. I'll have to get more done before I start laying them out to figure that out. ENJOY!
