I have bought one of these.
Not the Janome, but a Freestyle Quilt Frame!
It arrived in two big boxes, and Whippet X and I opened them tonight with the help of a good friend. The makers helpfully include a video explaining how to put it up and how to mount the fabric.
I haven't tried either yet - it was too late by the time we had watched the video - and it is unlikely that I will get any time this week. But I think once it is up it will be straight forward to use.
And it comes with a laser light - but there are no instructions for that. While I understand what it does, I am not quite sure where you put the paper. I'll report back once I have started to use it and worked that out (which won't be for a couple of weeks due to work and family commitments)
A new toy - I think it will make working with paper quilts a dream!
