I have been asked by a couple of ladies to explain the 3-6-9 block/quilt again. These number add up to 15 in some way, 9 + 6 =15, 5 x 3 = 15, 3 x 3 + 6 = 15.
I suggest that you have a large variety of fabrics I use about 10 - 15. This should be enough make a quilt about 60'sq then all you need to do is add a border if you wish. I cut up a fat 1/4 into 1 x 91/2' sq, 2 x 61/2'sq and the remaining into 31/2'sq's. I have found that sometimes one fabric will look fantastic in the stash but when you use it in the quilt it may overtake all your other fabrics. If you have a look at Slendour I have used a blue with white spot. I only used the 3" and 6" blocks because the 9" block was way to strong.
Select a combination of fabrics for your blocks and place onto the table or design wall to make up 15" blocks. Spread your fabric so that the same fabric don't get sewn together. Make up 16 blocks and join. I have made a quilt from my scrap basket and it look good, but the quilt above looks scrappy but, these fabric were critiqued throughout the whole process. I hope this helps. Send me some photos when you make your quilt and I will put them on my blog.
