I have sewing patterns (from smaller companies - not the "big four or five" in the USA, which would be Butterick, Vogue, Simplicity, McCall's, and Burda - which is European but available) - I'm thinking Stretch & Sew, Kwik Sew, Green Pepper, Saf-T-Patterns, Fashion Designs, Hot Patterns, and the like - which are NEVER "on sale" for a reduced price from the company. The prices start at $15 to $20 each and may be higher on some of the "imported from Europe" or hand drawn to buyer's measurements patterns.
Anyone asking me to make them something that means *I* am expected to buy another copy of the full price pattern and the materials is going to be told a very simple "no". If it is one of the Big Four (first on the list starting with Butterick) and I have a chance of finding the pattern "on sale" for less than $4 (maybe three to four times a year, depending on the brand & the release date of the pattern) - the answer might be "maybe".
But there are several hundred patterns in my sewing room that I already own - if you can find one that you like - your odds of getting anything sewn for you go up a LOT. They may still not get the item sewn immediately - there is a lot more to do in my life than sew for fun - reminds me - time to check the washer, empty the dishwasher, and get dinner ready. Anyone wanting to do the laundry, empty the dishwasher, and get dinner ready can volunteer to "help" so I can get to the sewing room before Friday afternoon.
