Cut out fabric. Large Bag : 28" x 13", Small Bag : 20" x 13"
Serge all 4 sides of fabric. (Sewing without a serger? Use the zig zag stitch on your machine!)
Fold fabric right sides together, short ends lining up, creating your bag. Stitch one side of bag with 3/8" seam allowance and iron open seam.
Press top serged edge down. From the folded top, mark down 1/2" along top of bag. This will be our fold line.
On the open side, mark down 1" from the top and clip into serging, stopping at 3/8".
Fold and iron in serged corner on each bag side. Fold top down on the 1/2" line, and stitch along bottom fold to create our channel. Cut drawstring. For large bag, 38" long, for small bag, 30" long.
OPTIONAL: Tare weight tag!
Cut a piece of scrap fabric 2" x 5". I used a coordinating solid scrap out of lightweight cotton.
Using a food or mail scale, weigh your fabric and drawstring.
On your scrap fabric, mark the halfway line with an erasable/water soluble marking tool. (This is our foldline). Also mark 1/2" from one edge of short side. (This is where out text will start stitching). Using the lettering feature on your machine, type "Tare Weight ___ oz" and stitch text, lining up drawn line with edge of presser foot. (On my Janome Memory Craft 15000, I used the Block text, Small print.)
One stitching is complete, measure 1/2" from end of stitching and mark. Cut excess fabric off tag, and then mark 1/4" on each short end, to fold raw ends in. Seam rip and snip extra stitches off. Erase pencil/pen markings.
Fold tag sides in 1/4", iron. Fold tag in half, wrong sides together, iron, and stitch short edges closed.
From top of bag, mark down 2.5" on open side and pin tare weight tag in place.
With right sides together, pin and stitch down the side of bag at 3/8", stitching right up to the bag channel. Turn bag right side out.
Tie one end of drawstring on safety pin and feed pin through channel. Remove string from pin and tie string ends together.
