I have been trying to cut some cards with less scorch marks and ash. This frame holds a sheet of A4 and replaces the honeycomb bed so there are no reflections making scorch marks. The top and bottom frames are slightly different to allow air to get under the frame. It works well, a piece of paper over the top collects most of the ash too.(svg here) And I meant to say this frame was made entirely from the scraps around the edges of the previous cuts, I have a few other plans for these areas too.
