Several years and moves later I found them in a basket while looking for something easy to work on while waiting for my mum having minor surgery. I wanted something that I didn't have to concentrate on too much, and this was ideal, since the outlines were printed on the fabric and all I had to do was to stitch those in black chainstitch and fill in with colours later.
The surgery went well, and my hours in the waiting room didn't feel too long, since I had something useful to do. I was amazed by how fast the work progressed, and kept at it after coming home. A few weeks later the tulip was all done and I went straight on to the sunflower.
The finished panels were about 12" - slightly too small for sofa cushions (I couldn't find any inserts that small, anyway) so I added strips of blue home dec fabric around the edges and used the same fabric for the back.
Once they were finished I gave them to my mum for her birthday, and I'm glad I did, because she was overjoyed.
