I am more than happy with my 1st purchase of flyers from printingcenterusa.com. They have been recommended by a friend that has used them, and I am pleased! French fold – the paper is folded in half horizontally and afterwards folded once more vertically to sort 4 equally sized panels. https://sethhvjvj.blogtov.com/10717359/not-known-details-about-flyer-printing
