I learned my lesson this past weekend. Was putting a project together and didn't want to do one part of it so I skipped reading that section. Sewed the blocks together and they didn't fit. I was bad mouthing the directions and took it all apart. I read the directions again to see if I missed something with the part I skipped. Guess what, in that section they told you to trim down the blocks. I deserved to have to tear it all apart. It was amazing how well it went together after that.
