Light Log Cabin
 

I so http://www.quiltershomemag.com/patte...html?idx=13608 want to make this quilt . But I don't know how to make it longer without losing the 3D effect.

I think you would need to add another row to the left and bottom. This would continue the 3D effect.

One easy way would be to add borders. I would use 1-3 of the colors in the quilt.

A second easy way would be to increase the size of the blocks, but this will increase the size in both dimensions. I believe the yardage requirement would increase by 3x
Changing to 3 1/2" strips would increase the size by 1.5. Strip lengths would increase to 6.5, 9.5 and 12.5". I believe the yardage requirement would increase by 4x.
Changing to 4.5" strips would increase the size by 2x. Strip lengths would increase to 8.5, 12.5, and 16.5"

I'm with Joyce888, though, to increase the size, add another column and row.

If I add to both the bottom & left won't it still be a square. I want it to be rectangular.

I've seen some photos posted in this forum of that quilt. lovely.

You could draw out rectangles in EQ7, and see what it looks like.

Otherwise, the only way would be to add borders unevenly, e.g., one on the side and two or more wider borders on the bottom.

One more thought. Try printing out 2 copies of the picture in the pattern. Then try overlaying the pictures. The first thing I tried was to take the top row to the bottom, but then the red is next to red.

Then I tried pasting the 2d and 3rd row to the bottom. But then there is a partial purple next to purple. But if you change the original bottom right to orange and keep the whole partial purple -- take the copy, leave the orange in the upper right, the purple half in the top row, then cut out the rest of the top row, and paste that over the bottom row of the original. That will give you 2 diagonal rows of the optical illusion. The quilt will be 3x5 rows. PM me if this isn't clear.

The 3x5 quilt I suggested would have
purple, red, orange
red, orange, red
orange, red, ORANGE
red orange red
orange red, purple

The red square in the middle would have purple in the upper left and lower right corners.

If your library has a copy of StrataVarious Quilts by Barbara Persing & Mary Hoover, they have a couple layouts of a similar idea in their book. I know they use a different technique & placement of colours but it might give you an idea on how to turn it into a rectangle.[ATTACH=CONFIG]415067[/ATTACH]

I just finished this quilt, and I made mine larger by adding borders. It is still square though. It ended up being 61 inches square. I added a two inch inner border and a five inch outer border.

I know that isn't what you are wanting to do, but perhaps it is a starting spot. If you made the top and bottom borders bigger...well, now I can't visualize that either, but...there ought to be a way to do it.

I will attach a picture of mine. It isn't quilted yet in the picture, but I haven't taken a picture of the finished product yet. I literally just finished putting the binding on it. Perhaps the picture will generate an idea for you that will help...

Dina, I see yours has passed inspection.
