WELL, just knock me up side the head! In all my searching for 10 1/2" UNfinished block patterns, I never noticed that the pattern for the Chain Link block says 10 1/2" finished! Here I thot I'd made a perfect sized block...I actually had to trim a bit off all around (which is usually not the case). It's an easy block to trim, so don't panic, just make it and trim a smidge off. Thanks Pam for letting me know.
