To download any of these files, click on the link, right click on the image, click on "Save Image As", then choose the folder where you want to save it. Open the file in any drawing and painting program, such as "Paint" in the WindowsProgramsAccessories folder. Use the line tool to draw diagonals in each square and the paint bucket to fill the spaces with color. Give the file another name when you save it and you can use it over and over again.

Let's
get complicated.... My “Pieces” Quilt 
For my Pieces
Quilt I turned the grid so sides of the squares are at an angle and the
diagonals of the squares are vertical (up and down) or horizontal (across).
Quilters say the squares are “on point”, because they sit on their points
instead of their flat bottoms.
This makes counting them a little complicated, especially around the edges where parts of them are sewn into the borders, but here's the design I used. 

For this quilt I started with a grid that has the squares at an angle. Quilters
say these squares are "on point" because they sit on their points instead
of their flat bottoms.

When I first designed
my quilt I was using this grid.
Do you see how the triangles go? In the first row across they are
all vertical, right? And in the second row they are all...which way?
I drew my grid and started coloring it in on my computer and didn't even realize I could change the direction of the triangles. 

Here is a grid with the squares
still whole. On this grid I drew a horizontal or vertical line through
each square to show how I wanted to sew my halfsquare triangles.
How many rows are there?
Can you figure out how many squares
I needed to make? How many triangles?


The big squares are where I put
the seasonal symbols. If I were to put squares in there, how many
would it take for each one?
How many for all four? This is the way I chose to put my
triangles.
To print either of these grids to make your own design, click on the image. To print my Pieces Quilt design with the symbols in place click here.


Here is my computer design for this quilt. It was the first time I tried designing on the computer and as you can see I wasn't very good. I'm still not REALLY good, but I'm getting better. I'm designing a lot of the quilts for my next book on the computer. It is a good way to experiment with color and check out a lot of possibilities before I cut the fabric. Do you want to design a quilt using halfsquare triangles in a program such as Corel Draw, Paintshop Pro, PhotoShop or others that let you "fill" spaces with colors? Download this jpeg grid file, open it in your software program and have fun!
