Miami Vice {a quilt top}

It has been very hot here in Auckland so I haven't wanted to spend much time with my sewing machine. I have however, been happily sewing together 16 patch squares.

In my head I call this my Miami Vice quilt because of the colour palette. Once upon a time I bought some Oakshott shot cottons but when they turned up I was never really in love with the colours. First I tried some hexies:

But I wasn't really feeling the love. So everything went into the cupboard until I saw this quilt over at Red Pepper Quilts. I like the way the colours look together now, so as far as the top goes, it is a happy outcome.

I am tempted to back the quilt with this lovely fabric but its voile. Which gives me the fear. Big time. 

Will a can of 505 basting spray and a million pins do the the trick? Or is it going to slip and slide and cause a lot of bad words around the place?? Adrianne told me that she backed a quilt with voile and that it went together ok. Mmmm. Will keep you posted.
