Not sure how your softwear deals with this but I know it is easy with PE design. I will check the details and post them for you
there is a free programme called Wilcom True sizer and you can change sizes and remove small stitches .... I use it and it is brilliant.....good luck ....Denise
There are two ways to resize: one way is to keep the density as it was, the other to keep the stitch count the same. The last method may give a dense design that might cause some problems.
However, test stitch whichever method you used.
Marie is right if you have reduced it it won't hurt your machine. I definitely would test stitch it on as close to the same material as the finished product will be. ;)
