I know it wouldn't be made of wood, but I have seen some of the pens that people have turned by using blue jean material soacked in CA. I am guessing you could maybe do the same thing with some BDU fabric. I would be interested to know if it was possible anyway.
I did this 2 years ago and to the best of my knowledge I may have been the first.
There are blanks made out of denim that cost $10.00 but they look like a pair of new folded jeans.I hate new jeans! I have penty of old ones to cut up and it doesn't takle that much CA.
I would estimate less than $2.00 worth if you buy it is 16 ounce bottles.even with a $6.00 bottle you shouldn't need to use more than a third of it at most.
(I use both thick and thin)
I wrapped the tubes of a pen with CA in layers and then turned them off after they hardened.
I had thought of it for Steve's "challenge" but it did not meet the criteria of being made out of wood.
From experience the pattern needs to be small and repeat enough because of the diameter of a pen.
Finding fabric like that in the pattern you are looking for is difficult I did try.
I believe my original idea(that met all criteria) with the printed paper is the most best way to come up with a realistic appearance.
AS far as turning paper, that too can be done.
In the above pen I actually turned of layers of paper and then put a CA finish on it.
After thinking about the challenge, the idea of cutting woods of the correct colors to get the desired effect though may be possible is not worth the amount of time involved.
It would depend on how many planes the design could be lay ed up in because ultimately it will be turned round.
The amount of pieces to be cut to give it a 360 degree effect is not worth the effort.
My original suggestion meets all criteria and would have the desired effect but certainly not worth the time for a
novelty pen.
