Harbor Freight is having a sale on their "carpet" (rotary) blades for $1.49 for 2 and their magnetic trays -6 inch round is $3.99 and the rectangle one (i think it is about 8"X4") is $7.99. Sale last until Sept. 30, 2011. At least at our store in Amarillo, Tx.
Stock up time. Maybe someone can save a little money to use on fabric. Ok, maybe a chocolate candy bar????
