I have often taught people who have never used a sewing machine to quilt. It can take a lot of time.
I tell them that we make a log cabin first because no matter what mistakes they make, I can fix them. I do it in my home because I have everything they'll need. That way they don't have a huge investment to make (other than the fabric!) to get started. Also, if they find they really don't like quilting they won't have spent $$ on notions. If they do like quilting, then they know what things they'll want to buy first. I go to the store with them to help them pick out fabric and at the same time I can teach them how to get the right amount and keep track of what fabric will go where, and teach them about batting. I use Eleanor Burns Quilt In A Day book. It already as the fabric charts and great instructions and yardage already calculated for them. Sometimes a picture is easier for them to see what to do than my telling them. It usually takes someone who know how to use a sewing machine about 18 hours to completely finish a quilt. If they don't know how to sew, 24 hours. I tell them that if they bring a friend along, it goes faster...as long as they can sew and talk at the same time! I have them tie the first one they make too.
As I only teach people I like. It's a lot of work and I gladly give my time to someone I actually enjoy being around. We pick a day that they have 7 or 8 hours that they can work. I set out some grapes and cookies and ice tea so they can snack, and I buy a variety of Weight Watchers meals that I microwave for lunch. Yes, it is an expense for me to do all that, but I enjoy it!
I have a large dining room table and counter. I set out one or two sewing machines, an ironing board, and cutting mat. The first thing I teach is how to fold and cut fabric. I tell them that the only thing I can't fix that they might do wrong is to cut themselves with the rotary cutter. I don't do blood. I show them how to measure, line up the fabric, and cut it with the cutter. The rotary cutter usually scares them a lot!!! I make sure that they close it immediately after each cut. I cut the strips for the Log Cabin a little larger. That way I can trim/square up the fabric as they go along so that they don't don't have exact seams, I can fix it.
After cutting a few strips, I have them use my easiest machine and teach them how to use it. Stop, go, seam guides, keep your fingers out of the way, and straight stitching. I give them some old strips to practice on. After 10 minutes or so they are ready to go. I show them pictures about how to line up the fabric from Eleanor's book, and demo for them. Since they are new to sewing, they sew very slowly! So while they are stitching their first strips together, I finish cutting more strips. Then I show them how to cut the strips apart and square them up and iron them.
Now, it could take a month if they had to do everything themselves since it is all so new to them. But after showing them how everything is done, while they sew, I cut fabric, and iron for them. If they have a friend, all the better. Before stitching all the blocks together, I make sure that they are the same size. Since I cut the strip a little larger, it is easy to cut them to fit. Putting the back, batting, and top together is fairly simple.
Yes, I put a lot into this, but it is fun! Some people decide that they really don't like the process, and others go on to buying their own machines and making more quilts.
