I looked in the archives and didn't really find exactly what I was looking for. I'm new to quilting so please be easy on me. I am making a Turning Twenty quilt. I have all my blocks finished and now I'm at the point of squaring them up. I'm sure I'll get several answers which is great but I would appreciate an explanation as to why you use your chosen method. The question is how do you prep your block for squaring up? Just pressing it? Press with steam? Press with starch? If you use starch what type? Such as light, heavy? You guys get the idea.

I don't want to miss any steps that will help me have a more accurate quilt. I am working on perfecting my seam allowance but it's defiantly something that takes time even when using a 1/4" foot.

Any and all advise will be greatly appreciated!!
