Second rug... fail

In my first ever rug post I used the same pattern as I have used here but I just kept making one big granny square.

The only problem is that I did slip stitch the whole way around and obviously did the tension too tight and now it folds in.

I believe that it is the tension that was incorrect but wondering if anyone else has any other solutions?

First ever rug

Finished my first ever granny square rug yesterday.... Or so I thought. I gave it as a present today and had forgotten to sew in one of the threads. So technically I gave someone an unfinished present. Not very thorough. :( sadly only realised as they opened it in front of me!

But I was happy with how it turned out and knew the person I was giving it to would appreciate it more than a store bought toy for their gorgeous baby.

I however underestimated the amount of yarn I would need and ran out of the purple colour. So my rug was a row or two smaller than I had wanted but figured it was still suitable for pram outings and the like.

I like the colours I chose and how it lay flat after I stitched the squares together. Just still kicking myself that I forgot to sew in the thread!

I got the granny square pattern here granny square pattern

It had pictures and explained everything nicely for a crochet newbie like me. A good granny square to start with.

joining granny squares is the page I looked at to decide how to join them.
