This jumper is made with two hexagons in the granny spike stitch. It comes in sizes from baby to adult. This pattern is designed to be made to measure so any weight yarn and hook can be used.

Materials

Dk / weight 3 yarn or any weight yarn of your choosing as it is made to measure.

I used Vintage Cotton purchased here in shades Purple, Lime green, Bright pink, Dark Turquoise, Coral, Lilac, Blue and Creamy Yellow (200 metres per 100g). I used less than 1 ball of each colour for size XL. I also used approx 850 metres of WI Premium acrylic from hobbycraft in black.

I used a 4.5mm hook for the main jumper and a 3.5mm hook for the rib edging

Pattern notes

• The jumper is worked in the granny spike stitch, which is like granny stitch apart from the middle dc is worked in the middle stitch, two rows below to make a spike in the middle, this also gives it a less holey finish. It is important when doing the spike stitch to pull the stitch up as high as the previous stitch or your work will start going pointed. If you struggle with this do a treble crochet instead (double treble UK).

• This jumper can be made in any weight yarn and hook, as it is made to measure.

•  I have provided details for dk yarn and the hook size that I used.

• The ch1 corner does not count as a stitch.

• The ch3 counts as a dc.

• Follow the hexagon until you reach the size you are making then continue to seaming sleeves, adding rows to the back and rib edging.

• Follow the size chart to add extra rows to the back, bottom and sleeves, or add as many as you need for your size.

• The hexagon will not lie flat, it will be wavy, this is how it should be, so that it can be folded in half to form half of a cardigan.

• Slst to the ch1 corner space to start the next round, if using the same colour. Or if changing colour join in any ch1 space.

• Each round of the hexagon is started with a ch3 (counted as a dc) and each row of the rib edging is started with a ch1 (not counted as a stitch) 

• I made the edging using a 3.5mm hook.

• My example pictures are for size XL. I made my hexagon to 8” then seamed the sleeves.

• To get the spike effect do two rows of each colour.
