I will have to try to drown mine in baby powder.. The advantage is that it's not greasy.. I mean, you can't really leave smears of margerine or mayo on playmoparts, right?
well, I did leave that 1 feather slathered in margerine in the name of not-very-scientific testing
but I wouldn't recommend it.
Left to right: baby powder / non-sticky / margerine
Not sure if you can tell, but out of the baby powder & marg feathers the marg one is slightly stickier, but both are better than before (which I think you can tell if you compare this photo with the one on the first post - which I added below to make it easier to compare - bottom photo is the pre-treatment one).
