DIY cover for outdoor couch from tarp

Here’s my attempt at making a homemade cover for our outdoor couch. Seems to work really well and I finished it in less than 2 hours. All I needed were the following:
1) medium duty tarpaulin
2) measuring tape
3) marker
4) scissors
5) flat iron
6) baking paper
Please be careful when using an iron to melt together plastic!!!
