I've had great results from the 8 at a time method mentioned previously. I too use slightly larger squares (i.e. 10 inch squares instead of 9 & 7/8 when I need 4 inch finished hsts) and then trim if needed. I really like the grid method Jan in VA posted - I will be using that next time I need more than 8 of the same fabrics. The 8 at a time is essentially the corner of her grid, so no bias edges either.
