letvia, as jrob said, mostly - she also told you that it might be too dense depending on the FSL designs - what one are you thinking of - perhaps - I could look at it and help you decide if it will work. *4U
Yep they are usually too dense to sew out on most materials :( ...BUT if you have a program that allows you to increase the size of the design but does not compensate for stitch density that might be easier to do tho...the size will increase but the stitch density will decrease (just like if you decrease size density increases with many...but not all... on board embroidery machine editing and some digitizing software size adjustments.)

Mostly, yes. Some of them are somewhat dense, so you need to take care what you are stitching on and be sure that it is stabilized very well, but you should not have a problem.;)
