Hello, I'm trying to design squares for a large crocheted bed covering, and as my brief web searches didn't find any advice specific to designing squares, I'm asking if the friendly knit-wits here had any general advice.
I've looked at a number of patterns for squares and borders, tried some out, and am making practice squares to test colors, patterns, and yarns (I've attached a couple 'sketches', but I'm still experimenting with the details). I'm thinking of having four squares that are crocheted into a larger square, and these large squares are joined with a simple border into the finished blanket.
My basic concern is am I making or likely to make some fundamental mistake in my approach? If I make a practice four-square, and it still looks fine after being washed, should I consider myself good to go?
