Hi, I've just gone into the Embroidery Library site, click on Designs by Category, go down page to Unicorns click on it and there are 3 pages of unicorn designs. Maybe your design is there. Good luck. Hugs from Maureen
Try googling “image of unicorn embroidery file “ you might find the picture there and company. Sometimes the beginning letters of a file can be a clue like KK = Kreative Kiwi or SD=stitch Delight. Sorry with my phone only it is difficult to help you in the search
