I generally charge for price of materials, then twice that for the labor. If it's a really difficult pattern, you might want to add on more. So, $100, plus $200 for total of $300 for a double bed size. About $350 for queen, etc. That's about the average price.

Too funny Scissor Queen!

For a simple pattern, I suggest the price of the material (backing, batting, thread too) and double it. If the quilting is super custom (feathering, line work, etc) I triple the cost of the material. It goes up if the pattern is original or more intricate. It truly ends up being around $500 for a simple, slightly custom (flowers/butterflies), full-size quilt. I don't think people realize what an expensive habit this is! :)

I think it's a hard question to answer. I'm working on a quilt for someone right now and I always have a hard time coming up with a figure. So now I do an estimate and give that to the person to decide if they want it done or not. I figure the cost of materials and then the number of hours of labor. I charge $10 an hour. I also give a range on both, then give the lowest and highest costs to them so they will have an idea of what I'm basing my total on. For the t-shirt quilt I'm doing now I estimated between $250 and 350. The quilt will measure 78 X 85 and is home machine quilted.
Good luck with your project.

Sorry, second thought of advice.
The worst thing you can do is sell yourself short! I had a friend that agreed to HAND BIND a 120"x120" quilt for $20!!! She would have given them a DEAL charging $100! She didn't know the person, so it took the "friend" element out of it. It's hard knowing what to charge a friend (if this woman is). If she is, explain that quilts are expensive and ask what she feels is reasonable and work from there until you're both happy. Regardless, deposits are non-negotiable!

I tell people "I'll help you make the quilt yourself. Here's the pattern, go to the fabric store and buy all these supplies and get back with me for quilting lessons."

I refuse to make quilts for people. It sucks the joy out of quilting and most of the time the person asking doesn't understand the time and materials that go into a quilt.

It is a hard question...a lot would depend on the kind of design/pattern you are making. $10.00 per hour minimum plus the materials and if you are having someone else do the quilting, the price of that in addition. I would definitely have the customer buy the materials up front.
I am making a quilt for someone, because he has done my taxes for the last several years at no cost, and I want to do something in return. He said he is probably getting the better deal. He may be right. I will be getting together with his wife to decide on a pattern. I plan on bringing an assortment of patterns that are within the realm of what I am willing to do, nothing too difficult, but nothing too basic either. Then we will go shopping for fabric, and depending on how much that costs, they may help cover the cost of that. We also need to decide on a size, and as long as it is a size I can machine quilt, I will do it as part of the deal, but if it gets too big, and needs to be sent out to be quilted, again, they will pay for that.
I want to do it, so that makes it ok, as I feel very fortunate to have had the help with the taxes.

Not that I have ever done quilting for anyone but I have done plenty of sewing for others. One thing I found out quickly is never hand the goods over until they have paid in full. Second thing was that most people do not appreciate how much time you put in to any project and are usually shocked when you give a price and I did not charge high prices!! Someone objected to paying my price for a tutu and when I wouldn't budge on price (it was a steal), they had to go somewhere else and ended up paying the equivalent of $120 more than I was charging :)

Please do not sell yourself short. Sewing is a skill and art, people always pay well for art and skilled work. Think how much it costs to buy clothing. I always charged $150. for a square dance dress 10 years ago. Quilts should go for a minimum of $500. for a twin and up from there. $15. to $20 an hour and always include the planning and consulting time. Long arm quilters charge form $100. to $500. or more, for their time and expertice. Your time and experience are just as valuable. Good Luck and have fun.

I only do things for friends, or friends of friends, and it is usually for a family memeber who passed away. I have 2 quilts that I will be getting Saturday morning that the piecing is started but grandma passed away before she could finish them. One is a Sun Bonnet Sue, and the other one has something to do with butterflies (havent seen them yet). I will charge her for fabric if I need to buy anything (always keep the receipts) and we will discuss how much money for my time. I don't expect much because people won't pay much. I also just quilted one on my long arm and the lady gave me a cute quilt hanging shelf.

I do it to help people get quilts finished, or to save a memory. I'm not in it for the money so much as to help out and also finish quilts that were started.

It would be nice to get $100 in addition to supply costs, but I really don't care. Since gas is so high i cant buy much fabric now and it allows me to still do new projects. :)
