DIY Snowflake or star (for purchased jumper)

Here's a simple way to make a normal plain jumper or cardigan (sweater) into something suitable for those 'Christmas Jumper' events.

Old plain navy purchased sweater.
A ball of sparkle yarn from an inexpensive shop.
A yarn needle.

I did a simple running stitch in the shape of my (slightly wonky) star/snowflake and then threaded the yarn through the running stitch tying off at the back.

It took  about half and hour to do.

I can always remove the yarn if I want a plain jumper again.
