there are no perfect quilts....it's ok to have a little oops
get the basic tools....glue stick for binding, seam ripper (will be your best friend), short and long ruler, good shears that are only used for fabric, lots of bobbins (when I start a project, I fill 4/5 at a time...great time saver)
Don't listen to anyone who tells you "you can't do that"....if you like it, it's ok!
