I hope to try and make my very first advent calendar this year!
I love cross stitch designs and have used several with no problems. I have stitched them on cotton and sweatshirts and they were beautiful. My machine does a great job, with no issues. Try one and see how you like it.
It's a good question, as the cross stitch designs usually stitch out more slowly, b/c of the denseness (?) and detail of the design. What appears to be a little design may take a long while to stitch out, but the results (especially from this site) are well worth the extra time.
