Hi, Betty.
There are many free butterfly designs in the Free Designs section.
Which design and designer aer are you wanting to open?
I have not seen the "download trail now" that you are referring to.
There are two options when you select the design you want to download - Ann's club and download design.
To download a design, click the second option. a twisting icon will appear as the file is being selected. Wait. A second download page will appear - click. This is the actual download and you will be prompted to designate run or save and to what location.
The designs will have two or more pages. The design, and data.
Download to documents, then copy and past or cut and past the design to your software. The data page(s) will be thread colors or in the case of applique, in-the-hoop directions and thread colors.
More information may be found in the tags (see below).
