Inspired by my previous post, I have created a series of 6 doodle sheets that are free to download. I have produced them at A5 size (though they could be made smaller or larger if you choose) and they can either be printed off and used as they come, or trimmed and laminated to make re-usable doodle sheets, as illustrated here. If laminated, they should be used with special dry-wipe pens to allow them to be wiped clean. I also punched a hole in the corner of each sheet and tied them together...
