I always buy my fabric from my LQS so most of the time it is not "real cheap" As it is I just recently made two quilts both different values
quilt 1: 2 x charm packs $16.45 each
1 metre fabric for border on sale for $10/metre
1 spool thread $8.95
1.6 metre batting $22.95
wide back backing fabric $24.94 (can't remember exactly)
quilt 2: fabric for quilt top including binding $174
batting $45 (bought more than I really need but couldn't remember size of quilt top)
wide back backing fabric $32.95
$10.95 for thread spool (buy one get one free)
I had both these quilt tops long arm quilted, the first one was for charity so no cost second one cost $122 to quilt.
So over all quilt 1 cost was = approx $90
quilt 2 cost was = approx $384.90
As you can see my quilt costs vary - (as do most other peoples I should imagine).
