When I am not satisfied with my efforts to use a technique in making cards, I try to learn from my mistakes. I used to just give up, but now I try to fix the problem. I was stamping images with Versamark ink onto white cardstock, embossing with white embossing powder, then brayering on ink to create a background. Some of my images turned out sharp and others looked blurred. You can check my previous cards to see what I mean. Here's a sample with 2 images with the same stamp.
Perhaps I'm heating the embossing powder too long, but I found another solution. I brayered on the ink first, then stamped and embossed the image. I like this method better. The image on the right was done with the 2nd method. Here's some cards I made using this method.
