Flip block - free patternThis week’s block isn't a standard block, but one made to fit our design. It’s a technique you will be learning which can be used in many common blocks. I refer to it as the flip-block.

This technique is an easy method of making an accurate block and can be used in blocks such as the very popular Snowball Block.

This method shows you how to make triangles using squares of fabric, so no triangles are actually cut. You can use any sized square (or rectangle for that matter) as the background section and add corners which can also be any size.

The idea of this technique is so you do not have to cut and sew stretchy bias seams as you would with cutting a triangle. A square is much easier to sew and keep in shape whereas a triangle (because one side is cut on the bias) can easily be pushed out of shape as it is sewn.

Triangle bias

triangles have a bias cut

For our sample we are going to make a double triangle block, but only on one corner.

Fabrics used in this block are: 2, 4 & 9. See all requirements here >>

You need to make FOUR of these blocks.

Cut FOUR 6 1/2" squares from fabric 2

Cut FOUR 4 1/2" squares from fabric 9

Cut FOUR 2 1/2" squares from fabric 4

Draw a diagonal line, from corner to corner on the WRONG side of all 4 1/2" and 2 1/2" squares.

Drawn diagonal lines

Draw diagonal lines through 4 1/2" & 2 1/2" squares

Position ONE 4 1/2" square, with raw edges even, in corner of ONE 6 1/2" square so drawn line is positioned across the corner, right sides together.

Stitch across the drawn line. Tip: By stitching ONE thread toward the corner from the drawn line will give you a neater triangle as you are allowing room for the fold.

Stitch along line and press up

Stitch along line and press

Press inside corner of 4 1/2" square over seam and there you have it, a neatly formed triangle.

Measure the block to ensure it remains 6 1/2" square. Trim is necessary.

Fold back the top section again and trim the TWO under sections back leaving a 1/4" seam allowance from stitching.

Trim lower layers

Trim two lower layers

Press triangle back in place.

For our double effect, you need to add the 2 1/2" square in the same way, on the same corner. Remember to have raw edges even and sew the diagonal line across the corner.

Add second square

Add 2nd square

Once pressed in place, lift the top section and trim away the TWO under sections to reduce bulk.

That's all there is to it. Now make the other THREE blocks the same so you have a TOTAL of FOUR blocks.

At the bottom of this post are additional quilts you might like to try.
