Display dome

These plastic tubes are generally found on the ends of individual roses.

Here you can see how I've used Leg blocks to hold the tube in place in my mitre box in preparation for a straight cut.

 The cut dome

 I found a wooden button in my stash that fit perfectly as a base.

 Not the best example of what to put inside it. VBG But it was the handiest thing available when I was taking the pictures. I actually have some Royal Doulton type ladies that would be perfect in it.
