Notebook Cover - The Sweet Leaf Recipe

Ingredients :
1 legal pad or notebook sized 11-3/4 in x 8-1/2 in
Cardboard 11-3/4 in x 8-1/2 in (The back cardboard of an old notebook works well.)
Fabric - outer cut 13 x 20 inches
Fabric - inner cut 13 x 19 inches plus 4 x13 inches
Batting cut 13 x 20 inches
Pockets 2 9-1/2 in squares with interfacing, folded on the diagonal

Consider thread-painting/quilting / embellishing the batting and outer fabric layers together BEFORE laying out for the final quilt sandwich. The batting can act as stabilizer.

Take the 4x13 inch strip. Fold and press under 1 in along a long edge. This will be the turning welt behind the notebook.
The secret is in the layering the quilt sandwich!

Layer 1 : Batting
Layer 2 : Outer Fabric (Face up)
Layer 3 : Corner Pockets
Layer 4 : Inner fabric strip (Face down)
Layer 5 : Inner fabric 13 x 19 in (Face down)
Note : The edge layer 5 overlapping layer 4 should NOT be caught in the edge seam. This needs to remain open for turning. [See photo below.]

After layering, pin to hold all layers in place.
Sew 3/8-inch seam around the entire perimeter.
Clip corners.
Use the turning welt to turn the inside out.
Work the edges and press.
Insert the cardboard to add body to the front cover. The notebook will add support for the back cover.

Here's a diagram of the inside view :

Here's a photo of the turning welt (Remember this live behind the notebook, so it should not gap open or cause problems.) :

Other options :
Add closures.
Add a pocket or clip for a pen.

Let me know if you use this pattern. I'd be interested to know if it works for anyone else.
