Well, I was looking for a garter carriage monitor, and hey presto, I found someone who was selling one. Someone up there likes me! 'Twas Knit N Natter day in Long Buckby - would've got loads done on the Rowan jacket, had I remembered to take (a) a tape measure, and (b) the pattern. Oh well!
Would have uploaded photos of my new gadget in action, but Blogger's being an a*se tonight.
Now all I need is the ribber brackets - had to drop it down to get it working correctly.
