Personally, I do not want anyone to be disappointed in any exchange - but you must remember those of us who have volunteered to manage the trades have NO control over what fabrics people buy and then put together, the post office, sewing or cutting skills, etc.
I always refer back to a national teacher who gave a lecture at my guild - she said when you are involved in a trade of any sort you must "learn to lower your expectations". I have been in many trades since I heard this statement. This philosophy definitely works - I use everything I get and am happier with the results.
I am managing the batik strip exchange and have gotten strips neatly folded into separate small baggies - such pretty packages!! Of course this is one person taking her time to make her own individual neat stacks - not 30 people working with 250,000 hst's, or in my case 23,000 strips soon to be sorted.
Everyone should be happy to have the opportunity to get involved - use your iron and make something awesome.
