Karin said: Beautiful finish. If I stitched the pattern I would finish it with a flat fold technique or I would use a foam block and do a no sew technique to make a cube.
Thank you all for your suggestions, especially to Laura who mentioned Sudberry candle screens which I had never heard of before and am now trying to justify spending a fortune on postage to the UK to get one!
Karin please let me have your postal address and I will get this out to you!
I have been busily stitching away on two secret pieces of exchange stitching so there's nothing to show you this week but I'll be back soon with an oldie but goodie for Kaye's Friday Frolics SAL!
