I guarantee to do the most professional job at my disposal. I, nor any other seamstress, am not a miracle worker. But I can promise to use the highest quality products on your projects. I can promise to take the utmost care of your fabric/clothing. I can promise to pay attention to each and every little detail. I can guarantee that if you are not satisfied I will work with you to make it right. Either you will get your money back, pay for another seamstress to correct, pay to replace, or fix what's wrong at no charge.
