Our LQS has from $5.95 to 9.95 a yard for 100% cotton and good quality fabric. Every month or so she also moves stuff on discount table to put in new stuff and that goes from $1.98 to $3.98 a yard.
Aside from the average LQS selling between $11-14 a yard I have seen some sell at much higher prices.
Our LQS has been in business for over 40 years and recently was sold to one of the employees and not much as changed regarding prices with exception of sale items going a tad higher but no more than $3.98 a yard.
Our local Walmart has prices similar to what is mentioned here but go to a neighboring town and it's a couple dollars a yard less and better quality and selection of material. Our local Walmart does not have good quality fabric even at almost $7 a yard. If I can put my hand behind it and see through it ... it definately is not good quality.
