If you're looking for the Liberty Fabric edition, I only have a fwe so they're all on Etsy.
 
This is so useful for anything you work from line-by-line instructions.  I designed it for knitting when the pattern is laid out as a chart (especially useful colour work) but I'm using it for written out patterns too.  It's also great for cross stitch and in fact any instructions you follow line by line.
 
Sandwich the instruction sheet between the front and back of the tracker, and move it up the sheet as you go.  The top ruler is made from clear acrylic (recycled of course!) so you can see the line you're on and - here's the game changer - the line you've just completed as well.  When you work from a chart you know that the line below is Very Important Information, as a reference to make sure you're working in the right place.
 
I made a version of this many years ago for my own use but I couldn't work out how to do it commercially, until I had a lightbulb moment while talking to Jenny at The Yarn Cake in Glasgow.  Thanks Jenny!  It's taken a lot of iterations and testing to get to this point and I'm delighted to be able to add it to my list of designs.
 
If you're buying from outside the UK - please buy through Etsy to have the correct tax applied. This should save you paying any local handling charge in addition to any tax.
