When we put jewels into a suncatcher, if you put a penny under them before soldering the piece, it raises the jewel above the surrounding glass and makes the jewels stand out and shows off their true beauty much more effectively.
For pin boards we obtain smooth white ceiling tile which can be obtained in 2 ft x 4 ft sizes at most home building suppliers. We then cut boards to the size we desire, put 2 together back to back with the edges duck taped. That way you can use both sides many times. The stained glass pins hold your work extremely well on these boards. You can also make larger boards when needed and you can see that in the pictures of “Noah’s Ark” on our website that we made a couple of years ago.
The reason we put 2 boards together is that they are much stronger and more rigid than just using a single piece of ceiling tile.
