One of my favourite things to hook up is bold graphics in Corner to Corner crochet. Here are two charts for C2C crochet blankets. One named ZZ Block and a bonus freebie named Ziggy.

This pattern includes the two charts, written instructions and tables with block by block, row by row colour order. There is also a “How To c2c” guide.

If using a 3.5mm hook and working in DK yarn your blanket will measure approximately 66 x 95cm / 26 x 37 inches.

If using a 4mm hook and aran weight yarn your blanket will measure approximately 80 x 110cm / 32 x 43 inches.

Yarn quantities & colours:
Double Knit blanket
I used Stylecraft Special DK (295m per 100g).

For ZZ Block you will need 2x100g balls of the main colour and less than 50 g each of the contrasting colours.

For Ziggy you will need 3x100g balls of the main colour and 1x 100g ball of each of the contrasting colours.

For the grey blanket: I used a non-brand grey (I suggest substituting with Stylecraft Special DK in Grey) for the main colour. The contrasting colours are: Stylecraft Special DK in Citron, Turquoise, Lobelia, Candyfloss & Fuchsia.

For the cream blanket: Stylecraft Special DK in Cream, Kelly Green, Mustard, Sherbet, Tomato and Lapis.

If making an aran weight version, you will need approximately 700 grams of yarn.

Notes, please read before making:

Work in the direction of the arrows to minimise snipping of yarn. You’ll have multiple colours attached at any one time but that’s better than sewing in loads of ends!
For extra help with C2C this video tutorial may help: https://www.youtube.com/watch?v=qkRDKp3As94&t=1163s it’s for a hat & cowl but the principle is the same.
The grey blanket pictured below has only two stripes (per colour) going horizontally (the bit where it changes direction) rather than three. Three means less yarn changes!
If you have tight tension I recommend going up half a hook size for your project.
The order of colour blocks are listed below for both blankets. You can use this instead of the chart, or in conjunction with it.
Regularly check to make sure the colours are correctly placed.
