Hope that helps a little! In my years of doing this, SWP is the cheapest program I’ve heard of that will do what it does! There are fancy designer programs out there and I’m sure they are fabulous, but this is what I use and recommend (especially for the price)!
*Regarding the comment, yes you can adjust the size of the design and add the name or whatever – it is all done on your computer before you finalize and send to your machine! I don’t like to adjust the size too much, but you can! It will not only increase or decrease proportionately, you can also click on the 4 corners and 4 middle dots and drag the box to increase and decrease (see the snowman’s scarf) or make the object wider or skinnier. Hope that makes sense! I’ve heard from one or two other people that the MWP extended features weren’t that great, but I don’t know anything about it!
