If you want to make a set of cushions using the same pattern as the pillow, in the solid granny square, then make fronts and backs of 4x4=16 squares.
The original pillow I made, I actually joined it with Aran weight yarn,
giving a slightly chunkier looking band to each square.
Both weights of yarn mixed work well and both seem to fit a standard pillow well, i found all my pillows were all slightly different anyway so you can find one that fits better if they make up slightly different.
The Aran yarn weighed quite heavy, so to give you more accurate weights i am making the second pillow totally in DK
and the weights below will give you more accurate weights in DK.
WEIGHT SO YOU CAN WORK OUT YOUR PILLOW OR CUSHION
All weights are approximate and slightly more than you will need dependant on your tension
6squares weigh approx. 20g
12squares joined together weigh 70g
working on all the figures you will need approx. 15g to make 4,
3 round coloured squares.
Approx. 160g to join 48square (pillow) together plus a few more grams for the button band and to join the front to the back.
For a complete pillow you will need 2 balls of background yarn
and approx. 15g x 12 colours for 48squares enough to make a complete pillow
BUTTON BAND DETAILS
By adding just 4 rows to one side of the open end will give you a button band that pops inside the pillow or cushion
space you 5 colourful button evenly across the button band
and use the joining dc (tr), stitch spaces as button hole how easy is that?
just push the button band inside the cushion, you can put a couple of stitches in the cornes but it isn't necessary i find, but you might prefer the look
Hope that helps when working out how much yarn you might need for a couple of pillows or a set of cushions
Maybe you prefer a blue version?
