Welcome!!
There are a lot of ways to quilt on a shoe string. Check garage sales and thrift shops for fabric -- both old clothes and yardage. I have also found some great quilting books at garage sales, thrift stores and used book stores (but I only bought these after I knew what authors are best). For good basic instruction, no one can beat Eleanor burns books -- she really takes things step by step and you can frequently find her older books cheap.
