I’ve read about the disappearing 9-patch so many times although this didn’t really take off here in Bloemfontein (maybe it did and I just missed it???).
Anyway Sally from the blog Sew Wonderful has a great tutorial for a disappearing 4-patch block.
You can find this tutorial by clicking HERE
Now if I can just get over my ‘quilters block’ (as in writers block and not a new quilt block pattern) and do this I too can claim that I’ve made a disappearing something.
