If the pattern is in PDF, I normally convert it to a Word doc...Then, the pattern is now an object within the word doc that I can resize as needed...This procedure also allows me to change the line colors to red for better contrast against the blade...I can also make the lines thinner to allow better precision while cutting...And finally, if I want to alter the pattern, I can use the drawing functions of word to add my own personalizations (I've done this on several of Steve's patterns).
