Good question. I recently got a set of fish bowl and Pocket type designs . Both use the plastic . Would be interresting to get an answeer .

If you use vinyl they will wash fine. I use lukewarm water and dampdry on gentle in dryer-though hang drying proably would be better

Smartneedle embroidery designs have squares of vinyl for this type of project. Jan

I wouldn't recommend using plastic or vinyl over the top of any embroidery.
Anything with a covering of plastic or vinyl over it will take a lot longer to dry, especially if you put it on a quilt or wall hanging which has got 3 layers of fabric- the top, the wadding and the backing. If it does not dry properly it will rot.
Both also sweat.That means the embroidery and fabric under the plastic or vinyl will remain wet for quite some time, and eventually rot as well.
Can you imagine what this does to the embroidery and fabric?
Plastics and vinyls will also become dry and brittle.
All you hard work down the drain!

I figure put those designs on things that you will not be washing, like tote bags, back packs, purses, etc. The same with Mylar designs.

Hi Betty, I have used clear vinyl on a table mat set. I think these designs would be machine washable cold definetly no dryer!
