I got the 3.25" Trim below
Use Clean Cotton Jersey Garden Gloves, or White socks on you hands.
Don't use 1/4" That's taller than the Sintra. You should use something closer to 1/8". You can get a "Ready Panel" 2' x 4' of Plywood Veneer at Home depot for not too much, strip it out in 2' lengths
Cut your Strips "the width of exposed Poplar"
Place one each on each side, at every corner, butting in from each direction. Glue these strips onto the Poplar. Now you should have a level transition between the outside edge of the Sintra, and the inside edge of the Plywood Strips.. A great "Nailer".Unless
by wonderful chance the "Cut IN" in the middle on the back of the trim will compensate for the extra height of the Plywood, and if the strips are cut just thin enough to fit but fill that space. It's not hard, even with a Hand skill saw. I know a "Finger-Safe" way..........
The last would be best of all. Requires a bit of measuring and precise placement, but perfection comes at a price.
