82 striped set blocks for this quilt
17 light plain blocks 66 of the dark plain blocks The width of your borders is extra fabric... quilt finishes without borders:
You need to piece: 10 1/4 strip sets of your light, medium and dark fabrics. For the frenzy quilt on left: Cut your strips 2 inches selvage to selvage. Sew them together using a very accurate 1/4" seam allowance. Use the "glob of tape" method or a seam guide to guide the fabric through the sewing machine. You want all the strips to measure the same width! You can have your "personal seam allowance" on this quilt, but just so all the strip sets are the same width. Press the seam allowances in one direction
for the strip sets. To the dark will be good. There is no matching
of the strips so it won't matter which way they go but just nice that they
all go in one direction.

Getting an accurate 1/4" seam allowance. You must have an accurate seam allowance! How to test? Cut three strips of fabric 2" wide. Sew the three strips with what you think is your 1/4" mark on your sewing machine. Press the seams of the strips in one direction. Now measure them. They should measure 5" across with the center piece measuring 1 1/2". If the set is smaller or larger, move your 1/4" mark and try again until it is right! Remember that pressing in one direction also takes up some fabric. I put masking tape on my machine to guide me. |

This is a strip set with fabrics cut selvage to selvage and pieced together... the five cuts at 5 inches will take up 40 inches of the strip. The same will apply for the plain blocks but there of course will be no striped fabric. |
|
| 1) You
will make 10 1/4 (or eleven if you don't want to cut a 1/4 strip
set) strip sets of three fabrics, light,
medium and dark.
|
|
| 2) You will cut squares
of the light and dark.
Don't cut your plain squares until you sew and measure your strip sets! The size of the squares will be the same size as the width of your strip sets. This will assure that your strip sets and you plain blocks are the same size if you used a larger or smaller seam allowance and your strips are a tad wider or more narrow than the mathematical measurement. This is a simple calculation that allows you to have "your
personal size" of strip. Sew your strips together for your strip
sets, then measure them in several different places. Take the average
(hopefully they are all the same!) and cut your plain squares the width
of the strip sets.

How to figure the fabric amounts you need for a specific other size
quilt:
| How many blocks do you need? | Use the chart on page 3 as a guideline for quilt sizes. | |
|
Take the number of blocks needed = |
Sample = 82 blocks | |
| How many block cuts can you get across the fabric strip? | For example, if you cut your fabric selvage to selvage your width
may be around 42"-44" depending on the fabric manufacture.
So if your blocks are 5 inches square,
|
|
| Divided by the number of blocks you need by the number of cuts you can get across the strip = | Sample = the number of cuts
you can get across the strip is 8 and you need 82 blocks.
So you divide 82 by 8 = 10.5 strips. You need to cut 10.5 strips of each strips set fabric. I would get a little more for safety and shrinkage, crooked cuts, etc. ... |
|
| How much fabric do you need?
Multiply the number of strips you need (round up) but the width of the strips you need =
|
You need 10.5 strips (round up to 11)
Multiply that times the width of your strips in the quilt = you strip width is 2 inches: 11 times 2= 22 You need 22 inches of fabric for those strips. I would get a little more for safety and shrinkage, crooked cuts, etc. ... |
|
| Now repeat for the other strips and the blocks = | ||
| How many plain blocks do you need? | ||
| How many can you get from the width of the fabric? | ||
| Multiply times the width of the blocks to the amount of fabric you need = | ||
