I read some Amazon reviews of Weekend Sewing (reviewed below) and boy are they harsh. (I like the book and have had no trouble with the one thing I have started) What is frustrating is that many of the issues that the reviewers complained about could have been avoided by always following these steps.
1. When you are making a new pattern,(or a recipe) read all instructions all the way through
2. Measure carefully (the old rule "measure twice, cut once" isn't just for carpenters)
3. Make a muslin to determine fit and any construction issues before you cut your good fabric
4. If the pattern is from a book, check the author's or publisher's website for any possible known errors. Threads Magazine did an article a little while ago on proofing your patterns. It's a good habit to get into. I have found many mistakes when doing this at the start and saved myself frustration and grief later on.

5. Ask for help if you get stuck. Don't give up! Many problem projects can be saved with some creative thinking. Nancy used this ingenious solution to fix an accident
What creative solutions have you used to save a problem project?
