The Opal 690Q sewing machine has similar modern innovative technology to the model below and has expanded on its features to make sewing easier and more enjoyable.  The exclusive sensor system has been designed to sense different thicknesses of fabrics as they are sewn for the machine to automatically adjust for better feeding. 
Unsure about tension? No problem this machinehas electronic tension and will automatically select the best reccommended tension setting for the type of stitch you select.  You can still override this and change the tension yourself. 
Have you ever been sewing and not realised you have run out of bobbin thread?  With the bobbin thread sensor, the machine will now stop and tell you when your thread is low before running out.
Save thread with the built in thread cutter.  This will cut both top and bottom thread automatically and save time.
