No one has mentioned that if you use that bubbly type of mat that comes with the close to my heart stamps under the paper it also helps with a good image. It is true that some "cheaper" stamps will just not cooperate no matter what you do. If you are coloring I have found that for me using OMS Momento was the only ink that did not run while I was coloring. The versa fine and memories both did not work for me, and I love both of those inks.
Don't fuss over a stamp that is cheaper and not working for you. Life is too short to get angry over our wonderful stamping hobby. This from the lady that spent and hour die cutting out little letters to make 7 "thanks" cards for hubby. The frickin paper kept moving and finally I just used a large sheet of paper and took only what I needed from the letters.
