I have light tracer II which is 12x 17, one light it is at an angle. I also have wafer 2 lightbox 2 which I prefer for applique placement. I use it all the time on mt ironing board with my wool mat next to it and my fuse mat on top. It has 3 light settings. I do like the angle of the light tracer better for drawing but if I had to choose 1 wafer would be it but it is also twice the price so keep that in mind. I find the wafer 2 to be a good size for my ironing board and projects, don't think I would need the three I just wish I got the smaller fuse mat
