Congratulations on the first sale of your 17 plane symmetry groups poster! It's terrific that each roll of the gift wrap = 6 copies of the poster, so easy to build up substantial numbers with just a few rolls... I like the way you've fitted the groups into the wallpaper sizing too - adding another option.
Sef this is such a terrific collection and handy reference to a vexed set of technical 'issues' to do with stuff on the diagonal - thanks so much for developing it and for sharing it! :-) Have you ever tested the degree of print skewing with these on fabric and/or wallpaper? I often notice that the weft (short side) of yardage is less than straight and that is likely to have more impact on say, the true bias in sewing terms. Just musing here: no need to respond - as nothing we can do about that side of it anyway...
The later connection of the elephant and, fairly randomly, the red colour to a US political party is quite unrelated. Sadly, the actual elephants don't get a say in the matter of having their reputation besmirched in such a manner!
