This seems like a good place to share a sewing tip once in awhile,,,,,,Sometimes a small inexpensive purchase can save time and make your sewing project easier.  Found this out when I purchased a refillable chalk pencil from the best sewing catalogue I know of WAWAK SEWING.  I check out the sale items each month in the catalogue they mail me and then go on their website to order.  They have good products at great prices. They send out emails with 2-3 day sales, too.  Fast shipping and good customer service.
