I purchased a very large lot (somewhere around 10,000 metres of designer fabrics and a few bolts of lace trims from a well known Canadian Fashion Designer 2-1/2 years ago for a VERY good price.
She was clearing some of her inventory to make way for the incoming new fabric trends - some of the fabrics were FULL unused rolls - in excess of 50 meters per roll.
2 months of intensive taking of photos, composing descriptions and determining my pricing, I eventually managed to get them all listed in my EBay Store.
It took me about 1-1/2 years to sell just about all - I think I only have about 120 metres left from the lot and I managed to make back my initial cash outlay and have realized a comfortable profit.
Was it worth the time and effort? Possibly but in hindsight, I don't think I will do it again as it took far more of my time and energy than I had expected and that of course took away from too much time from my other interests.
You would likely have far more success in selling quilting fabrics in a shorter time period than the designer fabrics I ventured with (these fabrics were for those interested in sewing their own garments).
You may want to seriously look at how much time and energy to want to put into taking on such an endevour but if you do and you're lucky, you could probably turn a good profit.
Good luck and hopefully, you'll post some in the forum - from the photos, there appears to be some really nice fabrics, etc.
