I do a lot of paper piecing and was looking for something transparent so that it was easy to reverse designs. I came across Simple Foundations Translucent Vellum Paper and purchased some, but it was £7.75 for just 30 sheets - although good, really expensive! I felt there had to be something cheaper! I hunted around and, eventually, found packets of Owl Brand A4 Natural Tracing Paper which, unlike some other makes that I tried, goes through my printer like a dream without jamming it up! Unfortunately, I discovered soon afterwards that the makers are discontinuing it so, 3 weeks ago, I went on the internet and tracked down a boxful which works out at £2 per packet of 20 sheets - only snag is ..... a box contains 144 packets!! But at least I shall never run out!! In the US, you seem to have much cheaper alternatives than we do here in the UK.
