You may remember I promised a tutorial for the Mid-Century Modern quilt, which I made and shared earlier this summer.
As I described in my post on how to use Excel to design a quilt, I start in Excel ... for this quilt, that looked like this:
For my tutorial, I have changed the color palette slightly.
Once happy with the overall design and color placement, I started laying out where the seams would be between "blocks" so that I could piece it all together. The red lines represent "sub-blocks" and the blue lines represent the "larger blocks".
The other thing that this layout does, is it allows me to quickly discover if I have made an error in cutting (which I did a couple of times), as the "sub-blocks" don't fit into the puzzle in the manner they are supposed to ... which I could quickly rectify before I moved much futher.
Here is the link to the Quilt Template that I made in Excel (don't know if it will actually work in Excel).
Next ... pick a place to start. Below, you will see a photo of my screen with the area outlined in gray that I have chosen to start with.
You can see where I have outlined a section 4 across by 6 down on the left. You will note the box just above the cells says 6R x 4C. This means the section I have highlighted is 6 rows down by 4 columns wide. I use this technique repeatedly throughout this quilt ... highlight the square and write down the R & C numbers in my notebook.
In my notebook ... Column 1 is the actual measurement that I have for squares, in this case it is 6R x 4C. Column 2 is where I convert that to inches (i.e. I divide by 2 since each square = 1/2"). This means that 6Rx4C converts to 3"x2". The last column is where I add for the 1/4" seam allowance. Since each piece will have a 1/4" allowance, I add 1/2" to each measurement, and come up with 3.5" x 2.5".
6Rx4C = 3"x2" = 3.5"x2.5" cut.
As you can see by my notebook ... I repeat what I did above, over and over and over again.
That "sub-block" becomes part of a "larger block" ... you can see it in the top right corner of the following photos.
These then get sewn together (you can see how I mitigated seams across either the colored blocks or the 1/2" connector lines).
Ultimately, these "larger blocks" go on the wall and are sewn together.
My only disappointment in this quilt top was that the two oranges were so similar in color. I didn't think they were that close in my sample when I pulled it together, but now that I have made the quit, I can see that they are too close ... oh well ...
As I mentioned ... PLEASE let me now if you have questions or I can shed light on what I did. As for material quantities ... I bought 1/2 yard of each of the colors and had plenty left over. The largest single cut is for the 9"x9" squares with the others being smaller ... so depending on what you want to use for the squares, you might even be able to make it from a scrap bin! The finished dimensions on this quilt is ~75" x 50".
All the best
