That sounds like a great advice Noelle! Thank you!!! I know my CB is old and a bit loose so several shims are needs and I run it through several times moving the die & paper to a different area on the plate each time (you know how those plates get warped & bowed), so that puts the pressure on a different area each time through.
These larger dies do take a bit more work, they even tell you that on the doily die manufacturer's video, but they are SO worth it in the end!!
