Mosaic Mystery Quilt ++ Square in a Square Units

Here are the Mosaic Mystery Quilt instructions for October...

Now that the Mosaic Mystery Quilt has ended, you can find a easy to print, full version of the pattern for sale in my pattern shop.

Square in a Square (SiaS) Units

1.  Combine 7 fabric A squares 4 ¾" x 4 ¾" and 14 bg fabric squares 4" x 4" to make 7 A/bg Square in a Square (SiaS) units 6 ½" x 6 ½" using steps a.-e.
         a. Cut each 4" x 4" square (bg fabric) in half once diagonally.
         b. Center a triangle 4" x 4" along a first side of a 4 ¾" x 4 ¾" square (fabric A).  Sew along the edge with a scant ¼" seam (shown as a dotted line), pressing seam open or outwards.

         c. Sew a second triangle 4" x 4" on the side of the square opposite to the first side, pressing seam open or outwards. (Note: you can sew both of these triangles on then press instead of pressing after each addition.)

         d. Continue by sewing a third and fourth triangle onto the square, pressing seams open or outwards.
         e. Trim off the tabs (dog ears) formed by the sewn on triangles and square the unit to 6 ½" x 6 ½" (if necessary) making sure there is ¼" between the corner of the inner square and the outer side of the unit.  Repeat to form a total of 7 A/bg SiaS units 6 ½" x 6 ½".

2. Repeat step 1 using 8 bg fabric squares 4 ¾" x 4 ¾" and 16 fabric C squares 4" x 4" to make                        8 bg/C SiaS units 6 ½" x 6 ½".

Many thanks to the generous sponsors of the Mosaic Mystery Quilt!

Any questions?  Leave them in a comment below or post them to our Facebook group page.  I look forward to seeing everyone's SiaS units.  The next set of instructions will be published on the first Thursday of November (the 7th).


  1. Hoping to sew up my units this weekend!

  2. OK - we are going to be gone for the last two weeks of October so this means I better get this done now. I don't want to fall behind. That never serves me well. :-)


Thanks so much for taking the time to leave a comment!
