Last night a friend of mine called me and asked that I make some signs for her. She wants them 2m long by 2m high. I was thinking of using MDF but then I thought of the weight. I need to recess the face of the sign in by 12mm. this will leave a raised edge border. I will the v-route the words for about 10 mm. I will then mount the sign between two posts. I am yet to decide on the material of the posts but I am inclined towards steel posts. Should I use MDF or is there any other light material that I can use? I welcome your views.
