Here is what naked grungeboard looks like. You can click on the pict to see the texture in more detail. Smells like bad leather when you open the package. A lot comes in each package. I used various paints on it. On the top texture, I used my finger. I put some paint on my board and rubbed my finger into it so I would only have a little on there. I put it on in a circular motion. No blobs or it covers up the texture. I tried sandpapering it but did not like that . I will have to experiment more with that. It is better to me to have contrasting colors. Light bottom and darker top texture. Other way will work, too.
I bought mine from Frances at heartsintouch.com. The textures are swirls, dots, stripes, and harlequin. There is a package called Elements and one called Alpha (alphabet). The alphabet one is much larger. The Elements have a lot of fun designs. Elements are about $8 a package and Alpha about $20 a package. Email Frances for specifics. email@example.com
You can see Tim Holtz demonstrating the grungeboard on YouTube:
Tell me what you think about it and how you have used it.
