funny you should ask....my DH just finished my boards last night. I had him do 10' boards as I have a king size bed. I think you might find it helpful to staple a strip of fabric the length of the board and make it so it hangs past the boards a good 3-4". My boards are 1x4s....the strip I cut was about 6-7".... DH stapled the length of the 10' board with this strip--reason--when I first wrapped my quilt top to the board I ended up with it being 'off' at the end of the wind...hence I had him staple the strip, this way I can pin the edge of the quilt top (and backing on the other board) to the strip and it won't turn on the wood. I hope this helps. I suppose you could also thumb tack the material to the boards, thus eliminating the need for the strip, but then you'd still have to unthumb tack them which I think the pins and strip would be easier. Good Luck!
