Very well done!
If you hadn't said that the covers were acrylic paint and stamps, I would have thought they were fabric. I really like how you stitched the covers.
The use of different threads makes these extra-special, too.
Congratulations!

What a clever way to use those cards!

This makes me smile! Great idea!

You did a really good job on this! Your stitching looks great and really sets off the jeans on the cover.
Good work!
