Do a large disappearing 9 patch corners made from sets of 3 fabric colors; center square - a solid color, the other 4 squares white (or the same color for each block). Play with if you need to rotate your 3 color blocks.
The cross-over block stitch is a really easy stitch to crochet - if you can chain, single and double crochet then you can crochet this awesome stitch. Really like this stitch! Must try for scarf or throw.
