I am in the process of making a crochet laptop case fr my 17 inch hp pavillion. I am using a cable crochet stitch. Im in the process of writing the pattern and putting up the pics but i fdid create a chart for it. It had taken me quite a while to understand cables and never really got it until i saw this video. The change i made, from the instructions given on the video was i wanted a 3 by 3 cross over. I haven’t figured out how publishers make the crochet charts that u see in books, and its not for lack of trying, so i use excel and copy and paste. Its a lil tedious but i like the outcome and i hope to become better at it and to make it look better.

cabled crochet pattern

Notes for the chart:

1. Between every row that is a chain three to account for the height  difference.

2. The first three red stitches are front post double crochets done 2 rows down and in the 4th, 5th, and 6th fpdc of the group of 6 fpdc.

3. The next three red stitches are fpdc done 2 rows down and in the 1st, 2nd, and 3rd fpdc of the group of 6 fpdc

4. To increase the width of the piece, use multiples of the 18 stitches.

5. To increase the length just repeat rows2 to 5.
