I have SewWhatPro. I absolutely love it. So easy to understand. I have it on both desk top and laptop.
I use Buzz tools and love it. Reasonable cost and does many things. Works as a library opening pictures of multiple designs in files, lists colors etc
Wilcom TrueSizer has free software, I used it for a year before purchasing software. Keep us updated on your choice and how well you like it.
Embrilliance is a great software, affordable as you can buy modules as needed. Hugs. Nan
Wings' "My Editor" is free for Windows OS. I think this might fill your wishes. It tells you size of design! Stitch count, and has 'redraw, which simulates sewing the design. Best is the full screen display of the design, and the ability to change colors, cut, merge, etc. I’ve used it for yrs even tho I have other programs that cost. There is a bit of learning curve, but good instructions manual with it.
There is another possibility. google for
"Embroidery Tool Shed Software" It is free
I believe it also comes with a download from DIME. You can select one of their free designs and it will come with that.
you need an embroidery reader to match your PC software, either windows or Mac. Embroidery reader is available for free on the internet. I myself use the OESD Artsizer 6.0 (free).
