Acquire as you go! Once you have the basics.. take it one step at a time..
ENJOY yourself as you learn. Don't stress over having everything at the beginning.
Buying is part of the fun, for me anyway!
Remember... re-purpose! re-purpose! re-purpose! re-purpose!!!!
If you are starting out in a dining room that has a table / china cabinet / buffet...
Use the table as your work surface. Place the machine at one end and cutting mat at the other.
Use the china cabinet for fabric storage and the buffet for quilting tool storage!
Eventually you'll find what system will work for you.
More than likely, you'll create your own personal system that works best!
HAVE FUN!
