1) Booklets.
Like quires for perfect bind or like centerfold saddlestitch.
A double bifolio is four leafs or eight pages. A n-ple bifolio is 2n leafs and 4n pages. 24 pages can be made as either three double bifolios or six bifolios in each other. 64 pages can be either eight double bifolios or sixteen bifolios in each other.
Pages are couples so that extremes of each quire go together.

2) Aerosol Stencil.
A sheet you put between aerosol and object to spray a text or image onto it. Here I deal with text.
a) print or write it on a paper
b) stiffen, either by glueing on to carton or by adding simply adhesive tape all around
c) cut out the letter shapes.
Now, this is the tricky part. Getting good or at least adequate shapes for even 36 p printout (in bold print) resuires some ado, but here is how I went about it. Each line of the text is cut into half (do this for first line only, then do following steps, then go back to do this to next line). Every pole in upper or lower half of a letter is simply excavated. Perfect rounds like letters o or upper and lower round of printed g - certain printing styles, not this one, which is like a handwritten g - are excavated. Any round or branch close to pole is excavated - cut out - except for part closest to pole (a is thus a pole to the right, an upper branch nearly attached to it to the left and under it a half round nearly attached to it, d is a half round nearly attached to a pole on the right, in b the half round and the pole change sides). Any turn is not cut out right in the middle: upper case U and this lower case g both have a bridge in the middle of the lowest part. Either upper or lower case V has the second line only close to first, not onto it. Anything not reachable directly from the cut up side - like a dot over i or accent over é or lower curls of the print only lower case g - will be reached through a slit of the scissor, which afterwards is scotched over. When all is cut out on both sides, put them together again (this is where it is real good if you used card board), scotch outer sides so as to keep anything between real straight as it ws before cut, put over weaker scotch in the middle and before repairing around each letter with small pieces of strong scotch, cut the weak scotch through. When all lines are thus repaired, scotch over any spot of unscotched paper without covering any hole. In the following example there were such cuts three times (or actually not quite the first line, which made cutting out letter shapes harder):
