Cold Spots in the Universe, Purse Stitch, Garter Stitch Stripe

1. Cold Spots in the Universe

According to a Guardian article on astronomy, there is less dense area in the Universe with is 20% less dense than the rest of the Universe. This is unusual because the Universe is fairly evenly distributed. This area is also a cold spot. It's 1.8 billion light years across.

2. Purse Stitch

Purse stitch is a rather pretty lacy stitch. It felt a bit awkward for the first two rows, but then I got into the swing of it. It's quite easy in that there is no need to keep track of which row or where in the pattern you are as it's a very simple repeat. It's consists of a single row on an even number of stitches.
