I have done many pressed flower projects, but this is quite impressive! Take a look and see the talent of this young lady and this
absolutely gorgeous creation of hers.
I have used a clear contact paper over cards and bookmarks and the color stays nice for years. I have done a glass piece, but after gluing the dried
flowers to paper, I used the clear contact paper over it before placing under the glass. This keeps air out and preserves the color for a very long
time.
