Instructions
Measure the distance around the middle of your flask, thermos or coffee cup with the measuring tape and then subtract one inch.
Lay the fabric and the felt on a flat surface in front of you. Draw a rectangle shape the length of the measurement you just calculated by 4 inches in width on the fabric with fabric chalk.
Subtract one inch from the length and width of the rectangle you just drew. Draw a rectangle with these dimensions on the felt.
Cut your rectangle shapes out with sewing scissors.
Place the right side of the fabric rectangle downwards on your flat surface. Center the felt rectangle on top of it.
Cut diagonally in a 45-degree angle across each corner of the fabric rectangle. This will allow the fabric of the coffee corset to be hemmed cleanly on each edge.
Fold the 1/2 inch of excess fabric around the felt rectangle inwards on each side and pin into place with sewing pins.
Sew along each edge of the coffee corset with your sewing machine.
Place the grommets evenly along the two short edges of your rectangle according to the specific instructions in the grommet packaging.
Thread the ribbon through the grommets from top to bottom in a pattern of your choosing.
Place the complete coffee corset around your coffee cup, thermos or flask, tighten the ribbon and tie it in a bow to secure.
