no fabrics are made here anymore. don't bother looking.
joanns has contracts with some famous mills. they weave to the quality that joanns is willing to pay for. in some cases, that's not great. kona is a good example. many people don't notice.
if you hold say, timeless treasures from joanns and from a LQS next to each other, you can see the difference. the LQS fabric is heavier and will hold up better.
the bias will be easier to work with, because the threads are closer. that's why it costs more. they're a little shop and can't afford contracts with giant mills. they have to buy at wholesale rates and can't afford to pass on huge savings. on the other hand, they pay more to get better.
joanns pay less for inferior goods and sells that to you, sometimes at the same price, sometimes for very little difference in price.
in the end, you buy what you can afford. sometimes that translates to online shopping especially when the sales bring the prices down to $2.99 and $3.99 and no shipping after, say $35.00 or even better, not at all.
everyone here has a favorite site online. i follow patrice's lead. she knows where the bargains are.
