it is best as you practice to work yourself up to bigger and bigger- going from a little 12" square to a whole quilt is quite a jump- go from a small square to a larger one- then a bit larger---until you are up to a baby blankee- then a lap quilt ect---- each new size is a whole new learning experience- having to control the bulk of the larger and larger piece- it takes time and practice for everyone- keep practicing- each one will be better than the one before.
