That is what I was going to suggest. I can do a lap size in a weekend.

I just found the pattern for a disappearing 16 patch. If you've got lots of different fabrics you want to get used up. Make up a bunch of 16 patch blocks - doesn't matter what size - if you've got a five inch charm pack, that would work. After you make the 16 patch blocks, cut them on the diagonal twice, then take two and sew the side seams together, which becomes the center seam. Creates a very interesting affect. Soon as I get a picture of the one I made I will post it.

I like the 9-patch pizzazz quilts from the book by Judy Sisneros. While I haven't done a disappearing 9-patch, it looks like a lot of cutting to me. The 9-patch pizzazz mixes 9-patches with larger pieces of a focus fabric, the kind that's so pretty you hate to cut it. Here's an example:

I believe the triple rail fence pattern is the quickest to make because after you've sewn strips together, you've made the blocks....all you have to do is cut the strips into segments and you're done. Color choice and placement can make this quilt dramatic and difficult looking. Here's a graphic of one I make.

Jan in VA

I use 3 color families, with 3 values in each family. Use a busy, wonderful print for the outer border; a narrow inner border of a color different from those used in the rails.

Cut your strips at 2.5".
Sew into sets of 3.
Measure across your sewn strips first to determine exactly how wide they are before cutting the segments.....probably near 6".
If you set 7 blocks across, 9 blocks down and make your borders finished at 1.5" and 6", your quilt will be approx. 57" wide x 69" long

Using a layer cake, stack 9 squares of fabric and using your long ruler and a rotary cutter, make a random, single slice through all layers. It's thick so you will need to be careful. Take the top piece of fabric on the right side, and put it on the bottom of the right side. Now sew the left side to the right side and press the seams. Keep them in the same sequence. Now stack them up and make another slice but going through a different direction. (for instance, the first time you did a vertical cut, now this time do a horizontal cut) Now take off the top two layers on one side and put on the bottom, and sew them together. You can keep repeating this until you are satisfied with the look of the crazy block.
The blocks will be very wonky when you are done, just pick the smallest one and square it up and square up the others to match it.
When quilting, you can use your decorative stitches on your machine.
This goes together surprisingly fast. When I took a class, a lady next to me had enough blocks done to do a twin size quilt for her granddaughter. It was only a 3 hour class!

You can sew the blocks together or separate them with sashing and cornerstones.

Here's the technique that I'm talking about but she uses fat quarters which would make it even faster!

Jan is right about the Triple Rail fence pattern - its super easy. I also like the 5 minute block - it isn't as picky as the 10 minute one. You can leave the edges as is or fold under for the curved effect. Here's a baby quilt I did using the pattern.

I love the tube quilt on Missouri Star.

This is my "go to" pattern when it needs to be done quickly. You can have it organized or scrappy. Here is a link to a scrappy looking one that I did late in 2011 as a gift. It was however a planned quilt - I had a stack of 9 golds and a stack of 11 browns.

Looks complicated but goes together like a dream.

Magic Square is another easy quilt that looks very cool.

I also like the disappearing 9-patch amd she won't knowthat it is easy or fast.
ood luck Ethel
