Thank you Lorra and Anne for your suggestions. I have found what I want on one site but the shipping cost is the 'killer'. The items are not heavy at all and when I selected $40 worth of bits and bobs, the shipping cost was $46! Here lies the problem.
Never mind, I will keep on making stuff and will keep looking. I buy quite a few supplies from US shops including heavier fabric and rulers and the shipping is no way near that expensive. Many stores offer half price international shipping these days and that really helps.
For interest, in Australia we are paying $20-$26 Australian dollars (AU$1 =US$0.94) for a metre of patchwork fabric (3 inches more than a yard) and I can buy the same fabric in the US for US$10-$12 + shipping, as you would be aware. Every patchwork and quilting item is at least double the price. I think we have been 'conditioned' into paying so much.
Of course, I do believe in supporting local stores, so I still buy things here..............................we are all 'impulse buyers' aren't we?...................that is all part of the patchwork 'condition'.
Happy and successful sewing,
Heather
