Use your surname, because you are an owner and a small business and not afraid to say your surname - your surname is your word of honor. It is all of your ancestors there with you, proud of you. It will bring you trust.
Use the word 'quilt', because when you do your website it will bring you up better to Google. You want your website to optimize for your town/county/state + LAQ/quilter/long-arm quilter etc
Avoid cutesy-girly-crazy type names because they are just short of ditsy which connotes unreliable - unless you can be wicked clever.
Good luck!!!! Do beautiful work!! Make money!!
