Well this is something I made for a friend of mine, her Dad was in the army during WW2 and although he's still alive and kicking, his medals have been tucked away for a long time. So she wants to give him them where they could be on display and this is what I came up with.
2mm acrylic sheet, clear is at the front of the frame. 3mm acrylic holds the medals and has the engraving of his regimental insignia. A third piece of clear 2mm acrylic sits at the back of the frame which is lined with stick on flocking. The flocking is black to show off the engraving but an area surround just the four medals has been removed from the rear of the frame to allow people to view the reverse of the medal.
Well I was happy with the result, like most engravers, a picture which had been in focus would have been a bonus but I can't say it was that bad in the end.
