This is very loosely based on a tutorial from Better Homes and Gardens. I made some changes to that pattern and the fabric sizes so am redoing the directions here so that I can follow exactly what I did again.
This takes approximately 2 FQ's of quilt weight cotton. One will be the main fabric and the other the lining. The pouch isn't fully reversible. You also need a cord or ribbon to close the bag of approximately 1/2 a meter.
Cut 2 squares of each fabric 8 by 10.5 inches. Cut two (one of each of main and lining fabric) circles 6.25 inches in diameter. This just happens to the the dimensions of a Fiesta bread and butter plate.
On the 2 main fabric pieces. draw a line one inch from the top and two inches from the top on both the front and back of the material.This is best done with a fabric marker that can be erased.
All seams are 1/4 inch seams unless otherwise indicated.
Sew the short ends of the main fabric together, leaving the space between the lines un-sewn. Sew to the bottom of this tube the 6.25 inch diameter circle. There will be a small be of easing to do as the fabric tube is slightly bigger (0.4 inches) than the diameter of the circle.
Sew the short sides of the lining fabric together and then attach the circle to one end of the tube.
Place each of the main fabric and lining fabric pieces inside each other right sides facing together and sew a seam along the top leaving a 2-3 inch gap for turning. Once sewn turn right-side out.
Top-stitch around the top of the bag closing the gap used for turning. My top-stitch line is approximately an 1/8 of an inch from the top of the bag
Sew along the two marked lines.
To make the cord: Cut a 2 inch strip X width of fabric. Turn over each end 1/4 inch and iron flat. Iron fabric in half then turn fold over each side to the middle. Iron. Fold down the centre and iron flat- Sew down one open side of strip about 1/8 to a 1/4 inch from the side.
Thread the ribbon or cord, using a safety pin, through the hole in the side of the bag.
