wow--REALLY???? i've been quilting for people for 10 years now---i would NEVER be so presumptious!
if a customer comes in with a batt i use their batt- or if checking the packaging it does not (work) with the quilting the customer wants we talk about that-the reason (like if the quilting needs to be every 2" and they want a design that will leave too much space between quilting lines) if the customer asks for a batt i do not have- i go get the one she wants! if the thread she chooses turns out to be a problem we talk about that--- i always get my threads out & let the customer choose (we spread threads out & decide together---and if i wind up having some problem with that thread i call & talk to her about it-before making any changes...I would not have given this person 3 chances---if it's not done right the first time (unless there's a good reason & communication has been open & honest) i would never go back- or give a referral- i'm quite amazed this person has customers.
