I found a package of putty knives at wal-mart for getting those straight edges. They are plastic and they come in 3 sizes.. 1 1/2", 3", and 6" for $1.88per package. I washed them in hot bleach water and they seem to work really well!!! I used the hot water treatment on them when trying to smoothe the top of my ccc and it works pretty well!!
thanks
just thought I'd share

That's great! Thanks so much for letting us know! I'm going to go buy some!! 
Hey! I got those same ones Wednesday night. Along with my new stencils from AC moore 
they were in the paint section. on one side of the isle was the rollers then i happened to turn left and there they were with like the masks and such..
if you don't find them ask an employee.. they are brown in color and come in a three pack it just has like cardboard holding them together.
here's the item number i'm assuming upc number
003706418836-
here the listing number (i think instead of having a stock name it has a number)
000370641883
