The heart and soul of any screen printing set up. Every ink mark and every colour stain tells a story!
99% of the time we print with square blade squeegees. 
Aluminium squeegees are super nice because they clean up easily, the blades are replaceable and they last forever.
Wooden squeegees are nice because the ink stains them and every time you use them you get a little more story on the squeegee - essential for those Instagram photos! The blades aren't replaceable though and they aren't as strong as aluminium.
