I got to my local copier shop and get a few copies of the plan , two reasons. one I put the original away to keep safe in case I have a glue attack etc, but the main reason is I always cut one up in to strips eg plan view, side view, any other views as you can open them easy on a bench to look at in detail quickly , I am not a fan of sticking them on the wall as it is not easy for me to take measurements off them , if I need templates I have a second plan I can use for them , I have a roll of double sided tape the thickness of selotope X 1/2 wide and putt a bit of that on the back near cutting edges. as you can pull it off the wood /plasic easy. I pay Localy £ 2.65 a full sized plan copy so it's worth it, photo copying at home on a PC can be a bit hit and miss because very few will do a good enough 1 to 1 copy
