Thanks so much. Actually I tried to match the colours of surrounding strips to the little 3 1/2 inch squares colours. Generally there were at least three colours in those little squares that I could match with Bella Solids colours.
I also, never created any kind of pattern for these. All I did was make one strip the same width as the little square, then the next two were made so that they matched the combined width of the little square and the previous strip width, and the last strip was made to cover the width of the little square in the two border strips. Super easy to make. Hard part is all the slicing and dicing you have to do. :-)
