Rainbow Quilt Block of the Month Block 9 

Welcome Back to the Rainbow Quilt Block of the Month designed by Janome Maker Carolina Oneto!  This month we will make our ninth block. The Star Cross is a quilt block that allows you to practice making HST 4 at a time and square in a square units! I sew all the blocks on my Janome 1600P-QC , which has a great Needle Threader, so you can quickly get your needle threaded so you can start sewing.


All blocks in the Rainbow Quilt Block of the Month will have a finished size of 12” so that means the unfinished size will be 12 1/2”. All seams are 1/4".





White background

  • One 7 1/4” square
  • Twenty 2 1/2” squares

Dark Green

·One 7 1/4” square

Light Green

  • Five  5 1/2” squares


Instructions for making HST four at a time:

  • Make four half-square triangles.
  • Place a white and colored fabric square (7 1/4”) right sides together.
  • Sew a 1/4″ seam allowance all around the perimeter of the square.
  • Make two diagonal cuts and press each piece open to one side.





Instructions for Square in a Square Units:


Mark the wrong side of the white 2 1/2″ squares in half once diagonally. Lay marked square right sides together with a light green 4 1/2″ square and sew on the marked line. Repeat on the diagonally opposite corner. Repeat on the other corners. Make 5. Unit measures 4 1/2″ unfinished.







Final Assembly:

  • Arrange your blocks in the correct layout
  • Using a quarter-inch seam allowance, sew together in rows. Join all rows, using a quarter-inch seam allowance.
  • Press your completed block and trim down to 12.5″ square (if necessary).












And that’s all!

I hope you enjoy this new block! And don’t forget to share it!
