Hi Bill, You bring up a very good point here which also is perplexing to me... how do I measure for the paper? I do come out short at times- how do I know exactly how much room to leave? Would love to hear the solution if you would be so kind? Thanks for bringing it up. You know, I spend so much time trying to calculate things (usually it ends up to be visually though) and it doesn't work sometimes, so, any info from anyone is very, very much appreciated- it's funny but I figured out very complicated tessellations this way where I came up with these realistic design patterns- everyone was amazed that I could do this visually. In school years ago I was so bad at math and here I could come up with these tessellations. It even surprised me! Anyways, I always love to learn new things to put into effect! Thanks so much for your help! abbe
