So the mat is finished. However it is too small to be a mat so I may buy a dowel to stick to the back and make it into a wall hangning. Also, I really like it so I might keep it for Emily's room.
Therefore, I have started another mat to send to Irene. It's got felt buttons appliqued onto calico squares and big blocks of colour between. It's quite nice to far. I have cut out all the pieces and figured out how I am going to arrange them so I just need to sew them altogether now. Shouldn't take too long.
