Bonnie was the only retail source for Icarex. Now that her business is in limbo, you need to contact Jon at Kites and Fun Things in Plymouth, Michigan. Jon is THE ONLY importer of Icarex into the USA. He uses the material to make kites for sale, but if you're polite, he will generally sell some. You might want to have a defibrillator available when talking to him about prices. The last time I talked to Jon he was very upset himself about the rising costs ... and he buys in bulk!!http://www.kitesandfunthings.com/
As Mike mentioned, Kite Builder is a well known supplier of nylon ripstop. He sells firsts and seconds in many different brands. You might have to bug Steve via the phone lines about your order. Some folks have had great service from him and others not so great. At the very least, check out his forum ... lots of great info there.http://www.kitebuilder.com/
Texlon is a fabric manufacturer in California who does sell ripstop retail. Just be aware that the fabric is only 54 inches wide. You can buy first quality or seconds from them ... seconds if they have it in stock. The downside is that you have to order in 10 yard/color quantities, but the price is very favorable. Seconds cost $2.50/yd plus a $5 cutting fee. Tony Killip (a club member) builds his commercial kites from Texlon ... first quality though. Jim Foster builds all of his personal kites from Texlon fabric. Call Martha @ 1-866-624-3999 to get the latest prices and availability ... and a color sample packet.http://www.texloncorp.com/
Another site that doesn't get much publicity is the Kite Co-op out of Texas. Read about them on their website. Barry only sells first quality, but his prices are very favorable. Call him to discuss prices and fabric. He sounds a little gruff sometimes, but he is extremely interested in getting kites (especially big kites) in the air so goes out of his way to help kite builders.http://www.kiteco-op.com/
There are other suppliers of ripstop, but their prices seem to be very prohibitive relative to the three places above.
Hmmm, you might talk Big Mike into buying and selling fabric as a part of his kite shop service.
