I've been meaning to try this since seeing Ricky Tims on Youtube a while back - he said he learned it in England BTW (just flyin' the flag! LOL) and I'd already thought of using that bias to get a cathedral window effect so thanks to both of you for reminding me! And as for the person who wants to stick to her own way - my Granny would have said 'there's more than one way to skin a cat'!
