Traditional Tuesday - Block 6

Block 6 - Mosaic
Working with half-square triangles takes some practice to get the points just so. If you are concerned with perfection, make sure you strictly stick to the 1/4" seam allowance when sewing, and pin generously. To hide the points if you're not worried about perfection, you can use a busy light print instead of the solid green.

I chose 3 fabrics for my block - one retro green print and two coordinating solids, green and gold.

From the green solid, cut 4 - 3" squares*
From the green print, cut 5 - 3" squares*
From the gold print, cut 1 - 3" square* (Note: You will have 1 extra half-square triangle leftover to use for something else.)
*If you don't want to square up after sewing, cut your squares 2 7/8" and sew with a scant 1/4" seam allowance.

The cut fabrics.
Draw a diagonal line from corner to corner on the back side of the lightest fabrics. Match up with a green print square, right sides together and sew 1/4" from the drawn line on both sides.

Cut apart on the drawn line. (The bottom shows after it's been sewn.)
Press to the print and square up to 2 1/2" if you cut your original squares 3". Just trim off the dog ears if you cut them 2 7/8".

Lay out the squares as they will look in the finished block.

Sew together in rows, pressing to opposite sides.

Join the rows together. I pressed these seams open because there is a lot of bulk at the intersections if you don't. Your block will be 6 1/2" unfinished.


  1. Oh, I sooo remember those 'old fashioned' calicos! I think I may still have some of them in a box somewhere. Think they have value???? Ha!
