Apron - the upped and lower part

In the begining I wanted to make it round, but I did some changes, because I think that the buttons wouldn't look so nice on a rounded edge.
So I put together the two parts F to F. In between I put the strip that goes around the neck. Pined it well and sew 1 cm from the edge.

Trimmed the exces fabric, took my overlock and sew on the edges again. After turning it around I ironed it and it was done. I wanted that red heart in the midlle.

The lower part I put together facing F to F and made a stich 1cm from the edge.

Made the same thing on the other side

So it looks like this.
