I bought my first sewing machine! At age 67.
The lady at the fabric store where I bought it gave me an hour's lesson on how to use it. It is a Janome and it is idiot proof. I am thrilled! A new world has opened up!

And unlike many other things in this world, I think sewing machine are made well.
I still use an old Singer treadle for this and that!
Sewing can be a lot of fun!
I used to make my own shirts, although since I discovered knit shirts, I've stopped. But I still have all of them, and now and then I wear them.
Have fun!
What are you going to make?
I make quilts with mine 
I thought maybe it was for the GrandDaughter but those linings will get you some practice and experience before you jump into a "project"
There's lots of patterns and inspiration on Etsy and Pinterest and just the internet in general.
and btw quilting is much easier than garment making (I think ) there's just a lot of steps.
Enjoy yourself,,,, the whole fabric & sewing thing is hugely entertaining, creative and addictive!!
Many years ago I had taken a class on using a sewing machine to make a double sided apron with a pocket.
I didn't have a class with mine, but there were youtube videos of how to use it.
I made my husband a pair of pants with it last month, the first real thing I've made, besides the sewing machine cover. Oh, I did make a kit for making a fleece blanket.
Sewing is a blast!
I wish I had a designated sewing area all to myself but my house is really small.
So now I'm more into knitting and crocheting because at least they're somewhat portable.
One helpful hint, if you don't mind, and you can ignore if you already know this...
Make sure you have an iron and ironing board handy for pressing seams and stuff. You'll likely be doing a lot of that.
One of my younger sisters sewed for years for her kids. Sewing was very good quality, but her finished projects always looked amateurish because she never took the time to press seams and darts, etc.
Anyway, enjoy your new machine!
