I have been purchasing from my LQS and notice that they actually seem to stretch on the fabric and very quickly move the fabric from the beginning of the measure stick to the end, never even laying it all the way flat. Last week I purchased 5 1/2 continuous yards plus several 1 to 3 yard cuts. I put them away but know I should measure them to see how short I am.
I am registered in several classes there over the next 3 months as I am just starting to learn quilting so I don't feel comfortable in correcting them when they are cutting my fabric (they have all been in the sewing business 10 to 30+ years). I am trying to walk a fine line of maintaining friendliness and there are only two LQS within a 30-45 minute drive so I don't have many options.
