How to use up leftover glass from frames ?

I also do my own framing and I use left-over glass to make floating glass frames. Very simple to use bookbinding tape (or any strong tape) to secure around the perimeter of two pieces of glass after "filling" the frame with a photo, old document, etc. I tilt the frames for display since I haven't figured out how to make a nice looking hanger for them. Good luck!

Nancy Hi,. You can buy a glass cutter at a craft shop. Try cutting the glass in different shapes, then adhere them together with copper and glue. This is how stain glass is put together. If you make them small, you can use them on a table and put a plant on top. You could with large pieces, use it hung on the wall and glue flowers to it. Aloha!

Pressed Flower Art Suncatcher

I made chalkboard frames to sell, so I always have extra glass. I love the pressed flower suncatcher. Thanks for asking this!

You could make terrariums with the extra glass. Use aquarium silicone to put the pieces together and it will be waterproof with no leaks if you put them together with enough to seal them well. That is all that holds the aquariums together, plus a small frame at the top and bottom. You can make them in all shapes and sizes.

You have the materials to make a portable green house. You could use a disposable aluminum pan (from the Dollar Store) to hold the soil. Make rows and plant seeds in each row. Then just lay one of your pieces of glass right on top of the pan. Place in a sunny location. The sunshine streaming thru the glass will create a green house effect. You could start all of your flowers and vegetables early. Then transfer to soil outside. This saves quite a bit of $$ and you can rest assured that there are no chemicals on your plants. Best wishes.
