In reply to elliot.baker:
Cannot help with laminating, but we have a flat OS map in a frame with thin perspex over it, with the frame screwed into the wall rather than just a hook/string so it won't move at all. Its next to our kitchen table and is used daily, by adults and toddlers and cats alike. We don't draw on ours like you plan to, but the toddler hits it and has learnt where the sea is, the cats bap at reflections on it, and the adults are endlessly planning routes on it. I'm not certain a laminated one would have stood up to the last 3 years as well as the perspex has, but that will no doubt depend on your lifestyle and who you have in your house.
Its definitely been a good thing having it up, and for us, the cost of building the frame (from wood we already had) and the fairly cheap perspex, has without doubt been worth the value we have got from having it up.
