Club EQ – Designing for a Charm Pack, a Jelly Roll, or a Layer Cake

Posted 05-01-2017 by | Posted in: Club EQ  

THE CHALLENGE: The examples I created have very simple blocks with geometric shapes that can be rotary cut from Jelly Rolls, Charm Packs or Layer Cakes with some easy planning for sizing. One fun thing I discovered is that once I have an overall kind of random placement of several simple blocks and color them with solid colors, I can then use the Serendipity tool to rotate the blocks and come up with several variations. Add in fabrics, and you can cross genre.

It is easy to design a quilt that works with each of these fabric collections once you have some idea about sizing for cutting squares and triangles from each.

A Charm Pack is a collection of fabrics that are cut 5” square.

A Jelly Roll is a collection of fabrics that are cut 2 ½” x the width of the fabric. The width of the fabric may vary, but the 2 ½” is constant.

A Layer Cake is a collection of fabrics that are cut 10” square.

All these fabric collections are delightful to use for scrappy quilts, since no one collection has enough of each fabric for an entire quilt. The variety of fabrics is desirable. You would have to buy several duplicates of the collections to piece matching blocks for an entire quilt, but then the charm of the variety offered in each packet is lost when you end up buying yardage.

Cutting Squares and Rectangles

From a Jelly Roll, cut 2 ½” squares to finish as 2” squares when pieced into a block.

Smaller squares can also be cut from a Jelly Roll.

From a Jelly Roll, cut rectangles that are 2 ½” by whatever length desired. These will finish to 2” wide when pieced.

Smaller widths for rectangles can also be cut from a Jelly Roll.

Cutting Half Square Triangles

A half-square triangle is cut by slicing a square in half diagonally. The straight-of-grain will be on the two squared sides of the triangle and the bias on the longest side of the triangle (the hypotenuse, if you remember from high school geometry).

Determine the size of the square to subcut by adding 7/8” to the size of the FINISHED triangle. For example, if the triangle is 1 ¾” finished, cut a square that is 2 ½” and then cut diagonally to produce two triangles.

From a Jelly Roll, which is 2 ½” wide, design the block with half-square triangles that are 1 ¾” finished. You will cut 2 ½” squares and cut them diagonally to get two triangles.

If you need half-square triangles that finish larger than 1 ¾”, cut them from Charm Packs or Layer Cakes.

(Standard “quilter’s math” tells us that you should add 7/8” to the finished size of a half-square triangle to find your cut size. EQ7’s rotary cutting charts follow standard quilter’s math, so you’ll see that it tells you to cut all those half-square triangles at 2-7/8”. Read  about a different method.)

Cutting Quarter Square Triangles

Use this cutting when you want to have the straight-of-grain along the hypotenuse of the triangle.

Determine the finished size of the triangle along the longest side (the hypotenuse). Add 1 ¼” for seam allowances. Cut a square to this adjusted dimension and cut it in half diagonally in both directions.

To cut quarter square triangles from a Jelly Roll, the finished size of the triangle would have to be no more than 1 ¼”. Any larger would have to be cut from a Charm Pack or a Layer Cake.

Designing the Quilt to Fit the Jelly Rolls, Charms, and Layer Cakes

  1. You may want to start with LIBRARIES > Block Library > Search > By Category > Triangles Only, Rectangles Only, and/or Triangles Rectangles. You may also want to check the EQ7 Block Libraries > 01 Classic Pieced > Simple Blocks.
  2. Select several blocks and Add to Sketchbook.

Now you’re going to have to work backwards from what sizes you can cut your block patches from your fabric to what size the block has to be to use those patch sizes.

  1. Review the blocks that interest you and evaluate how you might cut the patches from a Jelly Roll, for example. Consider the size of the finished rectangles or triangles. Size the block to work with these sizes.
  2. For example, the Broken Dishes block shown here, has 8 half-square triangles. If I want to cut them from a Jelly Roll that is 2 ½” wide, the largest triangles I could cut would finish to 1 ¾” (since you would have to add 7/8” to the 1 ¾” for seam allowances when cutting a 2 ½” square diagonally for the half-square triangle).
  3. Size the block at 3 ½” finished size so the half-square triangles could be cut from a 2 ½” square and sewn to finish at 1 ¾”.
  4. Size the blocks used in the quilt so the patches could be cut, including seam allowances, from a Jelly Roll, Charm, or Layer Cake. Note that when you size the blocks for a quilt layout in EQ7, you do NOT include the seam allowance in the dialog box. But when you’re deciding how to cut the patches from your desired fabric collection, you will have to remember to add the seam allowances when cutting the patches.

HINT: When in doubt, print the templates for your block and measure there, including the seam allowance, for rotary cutting your patches. The sizing will be accurate.

ClubEQ – Editing a File from the Quick Quilt Projects Folder

Posted 03-01-2017 by | Posted in: Club EQ  

The ClubEQ challenge for this month is to convert a traditional setting for a quilt in a Quick Quilt Projects Folder to a quilt in the Modern Quilt style. It’s sometimes difficult to define a Modern Quilt other than “you’ll know it when you see it,” but it may be helpful to include lots of negative space (often it’s white), solid colors or bold prints, blocks that may be traditional but interpreted in a different way with coloring, and plain borders. The two examples on the DoYouEQ website for ClubEQ this month are revised from the Quick Quilt Project named Sawtooth Chain. The two quilts started with the same traditional layout from the project file and changes were made to coloring, layout, and block design to create a quilt with a Modern look. For the challenge, you do not have to duplicate what I did for the examples. The challenge

ClubEQ – Add a Custom Color to the Coloring Palette

Posted 02-01-2017 by | Posted in: Club EQ  

The ClubEQ challenge this month is to learn how to add a custom color to the Coloring palette. This is a handy tool if you have a definite color in mind. There is an industry standard through Pantone that offers the RGB recipes for most colors you find commercially. The RGB formula is what computers use to generate colors, and it works differently than what we are used to when combining pigments in paints. Computers work with light. Each year Pantone announces the “color of the year,” and you will find a wide variety of items created for decorators, fashion designers, artists, and quilters, among many of those who create using color. The color of the year for 2017 is “Greenery.” It’s a very easy color to use, since it mixes with everything and is so very common in nature. “Greenery” has a special RGB recipe to make it standardized
