Cut all your wood to size for the frame here I'm doing a 1" mould by 5 1/4"x 5 1/2" ( size of the master block ) I will have then 5 blanks 1" x 5 ¼" . The wood frame is 2 length 6 ¼" x ¾" thick x 1 ½"high and 2 length 8 ½" x ¾" thick x 1 ½"high , Wrap all your wood pieces including the 3 m/m MDF base with glad wrap ( saran ) then make your frame.
Secure the master block to the board with double side sticky tape
