I do things differently with every quilt. I have even - gasp- machine-quilted a cople of items. Some of my favorite quilts have all the above in one quilt.
I usually wash and iron and starch my fabrics right before I use them. To me, it is like starting with a fresh piece of white paper in a typewriter. (Remember those?)
I also like binding on the bias, but it is not a hard or fast rule. Fabric does not lend itself to hard or fast anything. Generally speaking fabric arts are soft and slow but that is why I appreciate them so much.
I prefer to hand-quilt because I make gifts for family members and I love hand-quilted items myself (unless it is "Walmart quilting" by Indonesian 9 yo boys. Then it saddens me that they have to work instead of going to school.)Each person makes these decisions for a variety of reasons and there is no right or wrong way to do it.
