Tieing, tacking, basting! The differences between American and British English are always so interesting. In my mind, tacking is the same as basting, and I have learnt to use the word basting becasue it is used in the quilting world. (I had never heard it before I started quilting 11 months ago).I have never heard the word tacking meaning to tie. Is it just me or are other users of British English a little confused?
