Be sure to watch the video above for step by step instructions for creating this quilt block!

Envelope Top:

With the two 3.5” x 7.5” pieces placed on top of each other, make your triangle by maarking the middle of the top of this rectangle, ¼” from top. Using a ruler and marking pen, mark a line from the bottom right corner to that mark, repeat for the bottom left corner.

Using these lines as a guide, and using a ¼” seam allowance on the long edge, sew your triangle all the way around, leaving a gap on the long edge for turning. Trim around your shape, clipping the corners for sharp points.

Topstitch using a longer stitch length about 1/8 inch from the edge. This will also close the space you left to turn your triangle.
Your envelope top is complete!

Envelope bottom:

With the two 3.5” x 6.5” pieces placed on top of each other, sew all the way around, leaving a space to turn on one long edge.

Turn your rectangle inside out after trimming the corner for sharp points.

Topstitch as before, using a longer stitch length, this will close your opening that you left for turning.

Envelope Placement:

This depends on personal preference, but to make your finished block,
Place the envelope bottom on your background square, centered but a little bit down from middle. This was about 3.5” from each side for us, and 4.5” from the top and bottom. It doesn’t have to be perfect!

Sew your envelope on the background fabric, leaving the top open, and locking at the beginning and end.

Place your triangle over the envelope bottom, about ½” – ¾” above it. Sew this down onto the background fabric, locking your stitches at the beginning and end, careful not to cover the pocket.

There you have it – an adorable envelope block perfect for your Valentine.
