I have to tell you that my mom just got the martelli cutting table and it came with all the rulers and squares.... so far we love it. The only bad thing with the rulers is that once they are on the fabric they aren't moving. So you have to line up when you place the ruler down to cut. it takes a little getting used to that but it doesn't move so you aren't worried about slipping. The table although not cheap is great because we can raise it to my height for me and then lower it a few inches for my mom... I use it mostly when i'm down working on the long arm anyways but there have been a couple times that I have used the table to square up an end before i throw it on the frame.
