A long time ago, in a middle school art class we did some very simple beading like the coller at the top. But ours were just about 1.5" wide and 6" long, square. Not round!
But what we did, was get a cigar box, and cut 6-8 tiny slits at the left and right side of the box. Position the box so that the 'hinge' for the cover is away from you. If it has a pull off lid just put the slits at the two sides furthest apart. Then you put a long enough piece of string from slit 1L to slit 1R, and 2L-2R....etc. This will give you a sorta mini lume.
1L-------------------1R
2L-------------------2R
3L-------------------3R
4L-------------------4R
5L-------------------5R
6L-------------------6R
7L-------------------7R
8L-------------------8R
String 1 and 8, are the very out side strings, there are no beads out side 1 and 8. You then put one row of beads between each string 1/2,2/3,3/4...7/8, with the holes through the bead going from top to bottom.
1L-------------------1R
B1
2L-------------------2R
B2
3L-------------------3R
B3
4L-------------------4R etc.
A piece of really small string, goes over string 1, through B1, under String 2, through B2, over String 3, through B3. When you get to B7 you will finish by going under String 8, then you'll come up and over string 8 and back through B7, then under string 7, through B6, over str 6... the way to the other side.
You dothat about a billion times, tell you have 6"x1.5" worth of pattern.
To make the vest or garment, you could do this with 10"x1.5" pieces, then sow them onto a vest or shirt. Sorta like vertical 'planks' it would allow for the fabric to bend every 1.5" horizontally, and every 10" vertically.
Also, if you were to use 'pony' beads you could cover a lot more space quicker.
Another idea, is that I've seen some "kandi kids" make some pretty crazy shit with pony beads. I've seen top hats, bras, vests, and all sorts of stuff. Way back in the day I once even made a neck tie.
