You don't say how long you have been machine embroidering (ME), but no matter, we all need a refresher from time to time.
Please check two of my blogs: Stabilizer and Hooping those will assist you with your questions.
Also consider uploading a photo for us to review, we all have been there, so we want to help. The AnnTheGran (ATG) community is one of the most knowledgeable and helpful I have ever seen.
