What with box-pleating, tesselations and pattern grafts, I reckon most of us must have folded a fair few grids in our time. I just wondered if anyone had any tips on how to do this accurately and/or quickly (obviously the two may not always go hand in hand). Not the most exciting of topics, I admit, but one relevant to most of us.
My tip would be to alternate horizontal and vertical sets of creases - i.e. do horizontal quarters, then vertical quarters, then hoirzontal eighths, vertical eighths, horizontal sixteenths etc. I find if you do all the horizontal ones first, the corrugation effect it has on the paper makes the vertical ones hard to line up.
Do people make each crease separately, or sometimes crease multiple layers at once - and if so, how many layers before creep becomes a problem?
Do you make an effort to ensure that creases are broadly in the right configuration (mountain vs valley) at the precreasing stage to minimise reversals later on, or is this more hassle than it is worth?
