This is a standard craft/ floral foam, great for all kinds of projects, but I learned that it does not cut well with a knife.
This is the kind of easily compressed and punctured foam that is often used in vases to hold cut flowers, but it makes a good base for any kind of craft project that needs to support many stems or sticks. It can also be used to hold project elements until they have dried or glue has set.
In water, it completely absorbs the liquid and sinks, which is why it is used for flower arrangements. When not in water, because it is not as stiff as denser styrofoam it is easy to insert stems into the foam. You can do this several times, even though it will eventually break down too much to reuse. But it doesn’t have to be a perfect rectangular shape to be useful. I don’t know if it is all this brand, but I often reclaim blocks from the cemetery that have been thrown away to use for crafts.
I wanted a base for a dried weed arrangement to frame our Christmas nativity set this year. And I bought this new florist foam because I didn’t want any mold or smells from reclaimed foam that had been outside all summer.
This was in blocks that were 2 5/8 x 3 1/2 x 7 7/8 inches. I needed to split them to be only about 2" thick. I did this using a large kitchen knife. I managed to prevent it from splitting into multiple pieces, but it did tend to do what would be called a green stick fracture in a bone. It would be better to cut it with a hacksaw. No matter which you use, this foam will flake off small crumbs, so it’s best to cut outside or in a workshop because the mess will all have static electricity and be hard to clean up.
It can be ordered from The Craft Place
