Hi Aled,
I have done a bit of quilting, but wouldn't call myself an expert. I have a couple of books I got in a second hand shop. Some really good ones out there. Must say the Quilting mag is good!
Perhaps she would like some supplies? Batting can be expensive, especially if you go for the quality stuff. I use a shop at Cromford Mill in Derbyshire, but there are a few good ones online, too. New cutting mats and stencils are always welcome, especially if she would like to use different shapes for patchwork quilting. A new rotary cutter or new blades are also a good bet!
Hope this gives you some ideas...
