One repeat of the pantograph. Original size 6″
Print and copy to size needed.
Office shops that print usually have a proportion wheel so they can enlarge it to the size you need.
Cut off the name and picture at the registration marks on the first copy. Connect the registration marks and tape about 8 repeats into your own pantograph!
I like to use packing tape as you don’t need to be perfectly straight and it helps in rolling your new pantograph.
