Finished my first quilt!

It's nowhere near perfect, but it withstood washing (albeit at 30 in a pillowcase with 3 colour catchers), it's cute and it means I can move onto my next project! This cot size quilt took nearly a month to make but with large gaps in between stages and a surge at the end (did the binding last night and the quilting on sunday). I am pleased with it!The binding probably needs revisiting before the weekend when we give it! I single bound it with bias binding, but the corners are a bit sharp where the next piece was attached- any tips on how to sort this? I'm thinking about just wrapping the corners with slip stitch...
