I take my patterns to Office Depot and have them copied in red. At the same time they can enlarge them for me if I want. I don't do inkscape. I used an LED magnifier for some time but now only use the magnifier for an excellent light source. I have discovered I scroll better with a head magnifier. I don't have to swing a light out of the way when changing blades and there is nothing between me and the pattern. The head magnifier is cheap, has excellent optics, comes with five different power lens and is very comfortable. They are available on ebay for $10 - $16 depending who is selling them. They are all the same.
