Ok, lets ignore the rubbish light and 'design carpet'. The persnickety out there will also notice I've not shown any of the wedges an iron yet. This layout is subject to change, but this is where I'm going with it so far.
There is always one in the group that can't follow instructions. That will be me. Having printed and cut the template to slightly different dimensions to those marked on the template. I've also managed to cut 22 wedges, not the 21 that the pattern requires. I don't know whether I'll need that 'extra' or whether with all the seams sewn, I'll only need the 21. But for the purposes of laying them out in a nice circle there are 22. Rumours I am mathematically challenged are NOT exaggerated! I will start sewing at the weekend.
