matt,where did you get those 3 inch? glue spreaders/spatulas from,. the ones you were using when bending borders
not sure which ones i used? I have some that i purchased years ago and i have some i made myself. The ones i made myself are metal filler spatulas you use for applying filler. You can buy them from B&Q in different sizes. I then cut down trowel blades and pop riveted the blade on. I have also made some others from metal spatulas and then used a trowel cutting tool to cut my own teeth.
