I've never heard of this particular block but someone introduced me to this website with lots of instructions for different blocks and your Castles in Spain block was there. The URL is http://www.quilterscache.com/AlphabetizedListPageA_F.html. Just look up your block--it's all in alphabetical order. Hope this helps.

Can anyone post instructions for assembling Castles in Spain quilt block using three colors plus background color.
Thank you....
