Welcome :) This tutorial is for RIGHT HANDERS.
PDF Tutorial/ Instructions on how to make a crochet checkered bag. The tutorial is in English.
There is MINIMAL sewing involved, only to stitch the straps together. (EDIT: I found this pretty repetitive and straightforward, but some feedback showed that absolute beginners may take time to adjust. Editing the description to include this! Also, please do not hesitate to contact me if you find any errors in the tutorial or if you have clarifications!)

Dimensions of the bag laid flat (you can alter the number of rows/ squares accordingly to customize the size and strap drop. Instructions within the tutorial itself)
-Width: 37cm
-Height (without strap): 30cm
-Height (with strap): 47cm
-Photograph of where the width and heights are measured are in the tutorial.

Materials required:
-Yarn (the one I used is weight 50 ± g, thickness ~2mm). Total weight of bag is 215g (including the trim), hence, approximately
-Slightly more than 2 x 50g ball of yarn of desired colour
-Slightly more than 2 x 50g ball of yarn of another desired colour (photo of yarn hook with 1 of the colours I chose)
-4mm crochet hook
-Scissors
-4 Stitch markers. Alternatively, you may use safety pins (optional, but helpful to have);
-Measuring tape (optional, but helpful to have to help you measure if you want your bag bigger/ smaller)


Includes:
-Materials required and dimensions of the bag, with photographs.
-Detailed list of types of stitches used. This also includes instructions on how you can do all the stitches required to make the bag, such as chain, double crochet, double crochet decrease, single crochet and slip stitch. There is also instructions on how to change colours seamlessly.
-Instructions on how to crochet the bag with photographs to guide you along.
-The whole PDF is comprehensive, at 13 pages long.
