Gammill® CSQ File Format

The CSQ file format is claimed by Gammill® to be proprietary. However, there's nothing stopping us from defining CSQ for our own uses so I have created a document that describes the file format (CSQ V1). If there are issues, please raise them by following the link at the bottom of the page.

Gammill® Statler QLI File Conversion

Now that I have a Gammill® Statler , the QLI file format has been a little challenging so I created a file converter that is able to convert QLI files to the SVG WWW standard format that's supported in virtually all modern web browsers. This allows me to view the files without openning creative studio, hundreds of files at a time. The script was developed on Linux, it should run on Windows with the appropriate python software installed. The scripts are available here:

Rulers, Lengths and Angles

Need a ruler and all you have is a printer? You can print rulers and protractors and better yet, you can print them on a transparent sheet and viola, nice looking rulers on the cheap. You do need to make sure to not scale the print for these to work. Some printers have some variation in their ability to print accurately so make sure you understand how to do that.

The "Ruler Protractor" looks like the one below. If printed on transparent sheet, it's better to use the "mirrored" version so that the print is on the "bottom" side. These are meant to be cut from the printed sheet on the marked cut lines. It contains a 31cm ruler (12 inches) a 360 degree protractor and 2 triangles (45 degree and 30/60 degree).

Note that Acrobat does page scaling which kind of defeats the purpose of this so make sure you turn off any page scaling and make sure you have set the paper size correctly (to A4) and disable any page scaling when printing (set to None).


The "cm_grid_A4" files print a simple grid with lines marked every cm (0.5 cm in red) and graduations on the lines in mm. This can be used to measure complex shapes. I've used this to measure the hearts shapes so I could accurately replicate some pieces for a quilt.
