I usually cut out 4-5 blocks and then work on them all at once. Its just easier to have the ironing board set up to use for 4-5 instead of one at a time. Knock on wood I never get them all mixed up! I like to use a different pattern for almost every block, whatever the F8 "yells out at me" to do.
Cant wait to get aerinns F8 and send her a block then just sit back and wait for the remaining blocks to come home for Christmas!
