I think I must be the impulse queen having read all your comments. I usually buy what is left on the roll. My worse impulse buy was in a small country town when I went into a fabric shop that was closing down. We were going to be back through there in a week & I asked if they would still be open. She said she hoped not, all she had to do was sell all her stock & then she would close. I offered a price for the lot! Luckily we have a large station wagon!!!My poor husband muttered all the way to our holiday destination & home again.
