Recently started doing web design, and I love me some patterns, however some, like 'different vector pattern' (sorry cant post a link yet, its floral and widely used >_>), are pretty hard to see what the size it truly is just by looking at it. I ended up making a set of pattern overlay layers, side by side, and then transformed one till I could get the smallest size possible and it could be dupped above, below and left / right. There must be an easier way.
