i had 20 fat quarters. they were all different fabrics. from each fat quarter i cut four 8 inch squares. my quilt top is 4 x 5 blocks and measures 70 x 56 inches. i will be adding fabric around the sides to make it bigger before i quilt it though. (and i will update the above pic when i actually finish the quilt.)
i highly recommend that you have a 1/4 inch foot for your sewing machine. if you don't have one, you can pick one up for not too much at a sewing store.
1. first, figure out how large you want your quilt and then plan how much fabric you will need. (1 fat quarter will give you 1 block, 1 block measures approximately 14 1/2 inch square)
2. cut four 8" squares from each of your fat quarters. once you have completed cutting all of your squares, lay 4 of them in a square as shown below. find a circle item that is a good size. my circle is 10 1/8 inches across. try to stay within an inch of that.
3. trace around the circle item on to a piece of paper. cut it out.
4. fold circle in half, fold in half again so so end up with a quarter of a circle.
5. lay a few of your 8" squares on a cutting mat. place the folded paper circle in one of the corners. while holding the paper down with one hand, cut along the edge of it with the other hand. do this until you have cut all of your 8" squares. just make 2 piles, one for each half of the squares.
6. next, you are going to need to lay out all the pieces and make sure the fabric will be evenly distributed through out the quilt. i would recommend NOT doing this with children of babies around:) start by laying out all the larges pieces and then fill in the circles. i have heard that if you get a picnic table cloth with fuzzy stuff on the back that you can pin it on a wall and fabric will stick to it. that way you can switch around the pieces to see what looks best. make sense?
7. once you have layed you fabric pieces in the way you would like them to look once your quilt is done, you can start sewing. (i would recommend have a special room so you can leave your quilt layed out and no one will ruin all your hard work of arranging it correctly.) take one large piece and one small piece, lay them together as shown below. try to get it exactly straight and in the middle. make sure there is about the same amount of room on each side. i just eyeball this and it seemed to always work out fine.
8. beginning in the middle. start sewing a 1/4 inch inseam. (i highly recommend you use a 1/4" foot)
continue bring the fabric together as you go.
all the way until you get to the end.
it will now look like this:
10. now, flip your block around so the little piece is facing down. starting in the middle again. sew a 1/4 inch inseam as you did before.
it should now look like this:
12. now lay the square on a cutting mat. cut it down so it is 7 1/2" square by cutting the 2 ends of the large piece off.
sometimes, if the circle piece was not sewn on exactly straight, you will be left with a spot of no fabric like shown below. i just left mine like that, the space never exceeded 1/4 inch, it all worked out fine for me.
13. lay all your finished squares for a block together. sew the two bottom ones together and iron. (look at both pictures below before) sew the two top squares together and iron. now sew the top and the bottom together. iron. place your finished block in the space that it belongs where all the other unfinished blocks are.
