Depends on your own needs and uses. Space is the very primary concern. Design you quilting area to get the most from it. Planning makes it worth it all.
The basics from my point of view are:
- Good leaders
- Red Snappers for top and bottom, but not for sides as they are too hard for me to use. I made my own side pieces to attach my own clamps to
- A supply of thread for a LA. I buy as I need it.
- Extra bobbins
- Corsage pins , I bought 100 of them online, to anchor my side leaders [?]
- I also got the micro handles as they are easier for me to use.
- Pantographs, if you want them.
- LA rulers if you want to use them. I was advised to buy only 1 at a time to see if I really like using them. I don't, so it was good advise.
- A neck lanyard to hold my scissors for cutting threads and the scissors. I prefer the blunted/rounded end scissors so I don't accidentally cut my quilt fabric.
- A long tape measure and a notebook. I measure my quilts and then keep a record of the size and the patterns I use.
- A phone camera or a camera to record what I've done.
I also bought some fabric and batting to make extra quilt sandwiches for practice. You can then cut this up into totes, placemats or whatever when you are finished. I used to buy my batting in large quantities and it was well worth it.
Is it computerized? If so do you want to get more patterns, which are easily available on the net to download.
Time for at least 100 hours of practice. If possible take lessons as soon as possible, even before purchasing.
