How to brighten up a 'green' bag

As this month is Plastic Free July  I thought I would share this idea I came across a couple of years ago. I was in KMart in Mt.Isa and saw a lady with a Woolworths 'green' bag that had been embellished with yo yos and it looked very bright and cheery. I asked her where she bought it from and she said it was from the markets in Townsville. I had never seen these bags before that but have seen a few since then and they have all been decorated differently.
