Fireplace Vent Cover to Keep out Draft

Winter is in full swing in Minnesota
and cold drafts of air can seep into the house if everything isn't sealed up tight. 

Our fireplace has an intake grate on the bottom that leads out to the three season porch on the otherside. We've been blocking out the drafts by tossing throw pillows in front during the winter since we moved in six years ago!

I dusted off my "haven't used in forever" wood working skills 

and made my industrial arts/shop teacher  proud.  

I think maybe he would give this project an "A".

Yes I used my center island as a worktop.  Garage was just too cold.

I even lined the back with some leftover insulation!  That was the hubby's idea.

Pillows no more.  

Next task....spray the doors.  Looks like they've gotten a bit worn looking.
