Superior Threads have joined the list of companies providing titanium needles for home sewing machines. I have tried them and loved how long they last. The Superior website says:
These new titanium-coated needles have an ultra thin coat of titanium nitride layered on the surface to extend their productive life by five to eight times that of conventional needles. Most professionals recommend changing the needle every project or, if you count, every 8 hours. Imagine having a needle that will last 40 to 60 hours. This is equivalent to saving 80% on the cost of needles.
Tim uses Superior Thread in the APQS longarm machine with great success. Masterpiece is a fine cotton piecing thread he uses in the bobbin and applique lovers use for handwork. However, if you applique and want a fine cotton thread, you don't want to invest in a spool of each colour. So Superior created 'Frosted Donuts'. There are 36 colours of Masterpiece thread, each 85 yds on a prewound bobbin, contained in a bobbin saver. The 'Frosted Donut' retails at $48.99. You can use the bobbins in sewing machines but check the information at the Superior Threads website, http://www.superiorthreads.com/ to see if they work in yours.
