Gosh I have been looking at some lovely designs here but unfortunately most are bigger than 4x4 as that's the only hoop my machine uses. 

In recent times, a large selection of embroidery machines with large hoops appeared. Digitizer development projects, very often like a large size, because it provides an opportunity to make a more detailed project. Apply more color effects.
But we heard your wish, and we will do more projects for your hoop size.

That would be great, Thank you.

I do not know what software you use.  I use "Premier+ "  and have possibility to resize most of designs  up to  +20% or -20% without changing quantity of stitches and other sizes  with changing that.  I am satisfied with this software very much.
