I always carry a book in my bag. Mostly paperbacks because hardcovers are too heavy and these paperbacks get damaged sometimes because of other stuff in my (too) full bag. That is why I thought for quite sometime that I need a boekcozy with thick batting to protect my precious books.
I made 2 bags for 2 different common sizes of paperbacks: the small thick one and the bigger but also thinner one. Really thick books I just read at home and not in the bus 😛
Quilt fabric (cotton) for the outside, quilt fabric for the lining and cotton or bamboo quilt batting.
piece of 4 x 8 inches table cloth.
25 cm zipper (you can always make a long zipper shorter)
sewing thread and sewing thread in a matching color for the table cloth and matching color for the fabric of the outside of the book cozy.
zipper foot for the sewing machine
wonder clips and pins
Cut 2 rectangles of 18 x 26 cm from the fabric for the outsied, lining and batting. total: 6 rectangles.
Cut 2 squares of 12 x 12 cm from table cloth and cut each of the squares diagonally so you will get from 2 squares – 4 triangles.
Lay a rectangle from outside fabric right side up on a rectangle of batting and 2 table cloth triangles exactly above the corners of the long edge (that is going to become the bottom of the book cozy) also right side up. Hold them in place with wonder clips and sew the diagonal edge through. Repeat this step for the backside of the book cozy with the other rectangle of outside fabric, batting and the other 2 table cloth triangles.
Lay down a piece of lining right side up. Lay the zipper along the long edge down right side up and then lay above that a piece with the table cloth triangles. De zipper now lays exactly between both pieces. pin the pieces along the edge or use the wonder clips.
Set your sewing machine for sewing zipper with the special zipper foot and sew the edges with the zipper between them. Turn the pieces to the other size so the zipper apears.
Lay the other piece of outside fabric right side up. Lay the zipper right side down above the edge of the outside fabric. Lay the other pice of lining right side down on the zipper. It will lay on the other piece of lining. pin or clip and sew the edge.
When you turn the pieces you now have on both sides of the zipper 2 pieces sewn. top stitch with a matching thread to the right and left of the zipper all the parts 0,5 cm from the zipper on each other.
Open the zipper. Lay the pieces of the lining on each other right sides facing each other. Automatically the pieces of the outside fabric are aligned right sides facing each other too. The table cloth triangles are between and above each other. pin or clip the outside edges and sew around. Don’t forget to leave a 10 cm opening in the long edge of the lining (to be able to turn the book cozy to the good side)
cut the corners diagonally
Turn the outside piece through the opening in the lining. Neatly shape the corners.
Sew the bottom edge of the lining. Lay the lining inside the bag. iron the bag if necessary and close the zipper.
In the other bag I made the zipper is on the short side.
