I still use classical quilt techniques but modified to my style especially when I teach sewing.
I use the log cabin block and call it a magic square when teaching sewing. The first project of students is to create a square and then a pillow cover from that square.
They get to use scraps availabe in the scrap box that week to create their squares and pillow covers.
She placed those 2 pieces very carefully so that they would have a visual balance. Some of the students just "throw" the pillow together, others plan the placement.
The piilow covers have envelope closures.
I always find their different color choices interesting. I make sure to leave a varied selection of scraps in the scrap box and they delight me with their choices.
They can bring pillow forms from home and size the pillow cover accordingly. Or, they can sew an internal pillow cover and fill that with scraps.
She "forgot" to iron after sewing every strip down but she can still do it now.
Very happy with her pillow cover.
