Talking of colours, my latest thoughts are to do the borders black and then use red on the back (the images don't display the effect properly) and there is a black too.
I have just seen this hearts fabric in my local fabric shop, which would tie in with my heart theme on the front and the colours are right. it is only a small shop and they only have a few 100% cotton.
Have just booked for respite at Fountains Court after the Easter Holidays. Much in need of a rest, but worried about leaving Rob and Emily.
