Sometime ago one of my friends purchased something like this at the NEC. Her mother-in-law made several and they were sold in aid of the Air Ambulance. With the new material from SU, I thought I would have a go.
The fabric is Timeless Portrait. There are also papers and a stamp set in the same series.
I loved the bag I had before, but I have to say I like this one better. It really is useful, it keeps the floor and the table top clear so that I can make a mess with everything else.
Please don't ask me for a pattern, I haven't one. A bit like most of my projects I just do it, not very good at giving instructions.
