Rules are all good, but get expensive, have a good 6x18"(one you can read markings well),
a good cutting board (self healing),
a good rotary cutter (I love Gingher also, very long lasting blades, you'll save in buying blades over time..but one that works for your hand, wrist, if you have little ones, one that self closes is nice & locks. If you have arthritis, there are ergonomic ones)
Pins, that you can see, thin, long, easy to grab
Safety pins, curved if you plan to pin baste & the tool to help, even the pin covers are nice, ask they can help you.
some like to spray baste even with pinning or stitch basting.
The books, look for beginner quilts, the harder ones could frustrate you and you stop quilting. Build up. Then get the rulers according to the quilts you want to make. Ask for help.
Good lighting, good thread, quality fabric will help you not get frustrated. Working machine you know how to use.
A walking foot is nice if your investing in a new machine or get one for what you have.
1/4" foot or seam guides are nice to keep your seams accurate.
Square up ruler, square up blocks each one, so your end quilt will be also square.
Little snips scissors at machine
I love the Frixion pen by Pilot, at a Staples store, they disappear with iron heat. They have pencils and markers, but I really like this one best. 3 colors.
Depends upon the technique of quilting your starting... there are tools that help each block design. 1/4" ruler, paper piecing, log cabin rulers, etc.
Also a stilleto to push fabric under the needle without catching your finger, even that needle arm coming down gets ya.
Most of what you'll get quilting, you continue to add as you grow & learn & try new things. Always ask, here you get many opinions.. at a store, you'll get what they want to sell you (everything). Shop around, pins at Walmart or JoAnns are just as good as a quilt shop. Invest in good tools, especially rotary. A nice iron is important also.
Always jump in...
