Building Foundations Sampler QAL – Block 8


December got away from me! I know this is late, but I promise to get back on schedule and not make you wait so long for Block #9!

Block #8, the Gem block, from The Patchwork Book, 1932. The Patchwork Book was published by Women’s World Service Library and offered pattern for sale from Women’s World, Chicago, Illinois:

Block #8 Gem Block:


Background fabric, cut 1 – 5 1/4″ square, and cut 6 – 3 1/8″ squares. Cut 4 of the 3 1/8″ squares in half diagonally.

Accent fabric 1, cut 2 – 1 1/4″ x 5 1/4″ rectangles, 2 – 1 1/4″ x 6 3/4″ rectangles and 2 – 3 1/8″ squares.


1. Draw a diagonal line on the two 3 1/8″ background squares. Pair with two 3 1/8″ accent squares, right sides together.


2. Sew a scant ¼” on either side of the drawn line. Cut apart on the drawn line and press to the darker fabric.  



TIP: Square-up/trim your HSTs to 2 3/4″ square before moving onto step #3.

3. Join a 1 1/4″ x 5 1/4″ rectangle to opposite sides of the 5 1/4″ square, press seam to darker fabric. Add a 1 1/4″ x 6 3/4″ rectangle to each side, press to complete Center Unit.

4. Layout 1 HST and two background triangles as shown in Corner Unit Diagram; join and press seams open. Make 4 Corner Units.

5. Lay out Center Unit and 4 Corner Units as shown in Gem Block Diagram. Join two opposite Corner Units to Center Unit, press. Repeat for last two sides. TIP: Pressing these 4 diagonal seams open may help your seams to lay flatter.
