I have made 2 of the hexgon I Spy's (shown in the images in link above) with red triangles for my grandchildren and have 4 more sets of hexagons cut out for the other grandchildren. It's fun to collect the fabrics. I also enjoy the fussy work involved in marking and cutting out the hexagon...you can't rush the process so it's relaxing.
