Looks really nice you did a great job I agree with you on the chalk paint I use it all the time I just love it does the wax you can buy and you put it on and rub it out and looks really nice and it lasts a long long time when it's gone you just relax it again😊
my cutting table is an old solid core door on top of some left over used kitchen cabinets from that we got to upgrade our laundry room. I have an large cutting mat similiar to your which is well used and I made myself and ironing pad at the end of the door. I Love it.
