One of Road’s most popular $5.00 Lectures is the session with Bob Purcell, President of Superior Threads, where he talks about Thread Therapy. Bob has proclaimed himself a Self-Certified Threadologist, qualified to make diagnoses, give advice, and solve problems regarding thread issues.
Superior Threads began in 1998 as an at-home business by Bob and his wife, Heather, in their garage. Bob says that he needed to start the thread company in order to support Heather’s quilting addiction. Today, the business spans over a 25,000 sq./ft. facility in the red rocks of St. George, Utah.
The first product Superior Threads produced and carried was their Superior Metallic. They currently produce and sell over 40 different thread lines with more on the way. Superior Threads prides itself on seeking out the highest-quality raw materials and using the latest technology in processing to create threads for all types of sewing.
The most important warning that Dr. Bob gives is “don’t expect stores to know about thread and needles.” A quilter needs to become familiar with all the different thread and needle types in order to create the best projects.
Bob has found that most traditional quilters prefer using cotton thread but he stressed that there are so many other alternatives out there and he encouraged the audience to try new threads with their work.
Metallic thread is very popular but it also can give the “biggest headache.” warned Bob. He shared a way on how to see if a particular metallic thread is good or bad: Cut off a piece about 3 feet long and let it hang down. If it twists, it is a bad thread. Good metallic thread will hang smoothly without tangling.
Needles, Bob said, are the least appreciated and often ignored part of a sewing project. It is counterproductive to spend a lot of money on a sewing machine, fabric, and specialty threads and then use an old, worn, damaged or wrong needle. Bob suggested whenever beginning a new project, start with a new needle. Topstitch needles work best because it has a larger eye and a deeper groove.
Needles have a two-number system: the higher number relates to a European metric system measuring the size of the needle shaft diameter in hundredths of a millimeter. The lower number is a U.S. designation that is an arbitrary number used to indicate relative needle shaft diameter. Either way, the lower the number on a needle, the finer the thread should be used:
#70/10 for finest threads
#80/12 for 50 wt. threads
#90/14 for medium weight threads
#100/16 for heavier threads
Final tips Bob offered when using specialty threads:
- Use a high-quality thread on both the top and bottom
- Make sure the machine is threaded correctly
- Make sure there are no obstructions along the thread path
- Properly adjust tensions for the desired application
- Use the correct size and type of needle. Make sure it is inserted correctly
- Make sure the bobbin case is in good working condition
- Adjust sewing speed to compensate for other limitations
