cute. Years ago I collected the back boards from legal pads, when I had 30 I gave them a shot of 3M spray glue and laid a pre-cut piece of white flannel over one side. Easy to store and so nice to lay out blocks, stacked beside the machine. When I have a minute or two just sit down and go - not having to 'find my place'. They are in good shape after lots of use being slung around at retreats and workshops - and the glue has not 'crackled' or discolored the flannel.
