Amazon '#PrimeDay ' is neither a single day, nor is either of the days a prime number. And they placed it so close to the 23rd too. It's almost as though they we're even trying......
Found a quick reliable way to make stamp effects in Gimp.
1) Use a brush with 3-7% opacity to some irregularities
2) Use Noise > Spread
3) Curves as needed
4) Oilify
Protip: It won't work on an alpha bg. Also, oilify works better with black-on-white.

I tried digitizing and cleaning up brush strokes for my app today.
In #GIMP, use curves to color correct, then oilify. (Then 'color to alpha' to clean out the white, and then invert the colors to bring it in to #unity)
Oilify does wonders for making those edges crisp!
