Quilting patterns are often like that too. I purchased a kit from a really nice quilt shop. It has wool applique leaves on it. I was very careful cutting out the leaves but still was short of the wool fabric. I had to drive quite a long ways to go back to the shop to get more fabric. The owner had designed the pattern. She said I should have put in my instructions to lay out all of the leaves before you cut any. I could have told her that she also left out several other instructions. I ask her if I could take a picture of the quilt as it was on display. She said that was okay as I had already purchased the pattern and kit. I am making the quilt from looking at that picture. I would hate to think what an unexpierenced quilter would do with that pattern.
