Thank you all for your suggestions. Will see what the shop has in stock tomorrow and think about what you have all said. We are lucky to have three shops reasonably close by. I have already visited two of them when I bought the material for the top. None of them had a great selection of black and white, so I hope that the third shop will have a bigger selection. They are also very helpful for someone like me who is fairy new to quilting. I am worried that if I use a white batting, any stray black threads - how do you stop them showing LOL - from the fabric in the top may show through on the white border. I mean where stray ends unravel a bit, does that make sense? I will be machine quilting, fairly new but did meandering on my DS quilt.
