A question for people who have made big quilts eg @Bjay @Lilian @Sandra @Catllar @Ploshkin @Lowena @Iminei ... I'm sure there are plenty of others too.
My SS quilt will be approx 72" square when done. I'm not sure how to back it without buying a load more fabric than I need. With 44" width buying two lengths would be reasonably sensible but one I rather like is 60" wide and it seems wasteful to buy two lengths.I find this to be a recurrent problem!
After buying loads of fabric, sewing your heart out, you suddenly realise you need to spend a Blooming fortune on backing fabric £££
There are loads of extra wide fabrics now available ... flutter by John Louden comes in almost every colour imaginable ... and most decent Quilt shops will stock a range of extra wide ... but they do cost £££!!!
Alternatively you can piece the back, buy remnants from Quilt shops or Interior designers, use sheeting (wash first to get rid of sizing) or ask your best friends if they might have something suitable
Good luck, whatever you choose to do ...
