Having found this to be a problem as well, I found, at a local DIY store, an inexpensive device that solved the problem. Not knowing the correct name, it looks somewhat like a comb used for combing hair. It's about 10 inches long and the tines are able to move, with a little pressure, back and forth within the frame. One puts the device agains the area to be framed by the flooring and gently pushes the tines against the door frame, etc. When taken away, one has a perfect imprint of the design to transfer to the laminate flooring. Good luck...
