How do you do a search on this site? I have a design number but can't remember what it was. Don't want to have to put it on a USB and take it upstairs to the sewing machine to see it.

babash gave good advice. A embroidery program that shows a picture of the design and lets you convert to different format is almost a must. If you do not have one I am giving you a link to wilcome truesizer. It is free

If you have embroidery software on your computer you should be able to see what the design is. I have Embird if you don't have it you can download a free trial or there are some free programs which I am sure others will tell you about.
As for a search button for this site there isn't one which is a pity as I could sure use one at times.
Welcome to the Cute site I am sure someone with more knowledge will come along and help you soon people from all over the world on here.
