We Need to check the following thing before buying an embroidery :
1. Mirror-image capability - enables symmetry and balance in the pattern-creating process
2. Cutaway Backing - enables cutting the excess with a pair of scissors
3. Tearaway Backing - enables the excess to be torn away after fabric is embroidered
4. Automatic needle threaders
5. Bobbin: The spool that holds the thread. The stitches on the underside of the garment are formed by the bobbin thread

Also it must be from branded company.
