I bought the same pattern because I thought it looked so great. However, mine is still on my "to-do" list along with 18 other quilts. So kudos to you for buying and completing it. You should use it with pride since it looks great and no one but you will notice these errors. If you find you aren't using it, give it away and the recipient will enjoy using it and won't notice the errors that you only really noticed when you got to sewing that part!!
Congratulations and pat yourself on the back - Judy
