1-Set of No Parking Area Templates - Large; HO Scale (1/87); Foot print approx. 2.62"L x 2.51"W x .045" Thick; arrives unpainted with a white, versatile plastic finish only. Use blue painter's tape to hold the rectangle template (# 1) in the location you want and trace the inside box with a white or yellow marking pen. Remove the template and align and tape down the diagonal lines template (# 2) with the box you drew and trace each diagonal groove. Choose a marker that is fine enough point to fit comfortably within the template grooves. I use a white "stampin''" chalk marker purchased at stampinup.com under ink/markers. The marker ink drys quickly and you may want to recoat it a few times.
