Hi Michael,
USE SCRAPS!
No, seriously, if you have a log cabin pattern that is making you tense, use scraps. If you hate the first trial product, its an instant trivet/hotpad for your next picnic or patio get together! No loss, no shame.
Once you follow the directions using scraps and actually finish the first log cabin block, you will be amazed at how easy the next ones will be. Then you will have the confidence to cut that good fabric . . . or maybe you will keep using scraps?
I was also terrified of the first block, but soon realized I had met my new best friend in the log cabin.
Tracy.
PS: I really like Eleanor Burns books as well. Sounds like a gift idea to make know to your friends when they need to shop for you!
