what you can do with them:

You obviously sew them together to make cushions, afghans, scarves, placemats, or whatever you want.  You can also continue the same square and make one giant  square for a giant single-square afghan or something like that!

how to do it:

Start either by making 4-6 chains and ss in first chain to form a ring, OR use the magic loop method, whichever you prefer.

Round 1: ch5, dc4:

Next, ch2, dc4, ch2, dc4, ch2, dc3,

Then, ss in 3rd ch.

Round 2: ss in the space of the corner (the 2 ch space):

Next, ch5,  dc2 in same sp:

Then, dc in each of next dcs:

In next corner space make 2dc, ch2, 2dc:

go around like this until you get to the end of the square:

then  make 1dc in the first corner space:

Finally, ss in 3rd ch:

Rounds 3+: repeat round 2 (you should have more dcs along the side of the row with each round you make):

And that’s it!  London Mummy did 3 rounds in color and the 4th round in a cream color, then stitched them together (I’m not sure which method she used for that — there are many available).
