Thanks for the info everyone.
nativetexan - have looked up Sewers Aid and just need to have a look to see where I can get it here.
Katrine - love the look of the gold fmq on black - just stunning.
I am not working today so am visiting my mum (an hours drive away) and pass a quilt shop on the way. I will have a look for silver metallic thread/needle/Sewers Aid.
Decision time this weekend.
