This is what you will need:
13 Granny Squares of your choosing - a 12cm x 12cm (about 6 rounds) gives you a fairly convenient size bag - for this particular bag I used my EIGHT PETAL GRANNY SQUARE PATTERN - with 1 extra round of DC
Yarn to work them together - I prefer to either single crochet them together on the right side or use my VISIBLE JOIN
About 25g of yarn for finishing and the handle.
I find that a granny square made with DK (in whatever blend you like), using a 3.50mm to 4.00mm hook gives a nice soft but sturdy fabric
Arrange your squares as follows:
NOTE: Squares 3 and 5 coloured in green are represented on both sides of the pattern (2 squares only - not four) I have represented them this way because these two squares fold in half, and are worked into both the front and back of the bag. Once you have joined your squares as the diagramn indicates fold along the bottom of square eight. Fold squares 3 and 5 over and join. Join the side f 1 to 12 and the side of 2 to 13
Crochet two rows of sc aound the opening (doing a 3sc tog over the "v").
I only made one strap (handle):
Foundation Row: ch 120, sc into 2nd ch from hook, sc into each chain to end, 1ch then turn
Rows 2 - 6: 1sc into top of each sc from the previous row
Fold over and then work Row 7, sc into top of sc on previous row and through corresponding start chain (so you will form a "tube")
Centre the handle over the joins for squares 1 and 12; 2 and 13 - sew in
The bow embellishment (optional) is made as follows:
Piece A:
Foundation Row: 13ch, sc into 2nd ch from hook. sc into each chain to end
Rows 2 -5; 1sc into top of each sc from the previous row
Piece B:
Foundation Row: 8ch, sc into 2nd ch from hook, sc into each ch to end
Row 2: 1sc into top of each sc from the previous row
Fold Piece B over Centre of Piece A and secure tightly to form a bow.
