Computerised machines give you a larger number of stitch functions. Instead of a manual dial to choose your stitch pattern, there will be a button or touchpad. Computerised machines start at around £150. Depending on the LCD screen, a number corresponding to the stitch pattern chosen will be shown or a sample image of the stitch pattern. Many machines have embroidery patterns and on some more expensive machines you can upload your own designs or designs from the internet.
Some computerised machines add the ability to sew without a pedal by selecting the speed on a slider on the front of the machine - a pedal is always included in case you wish to use one.
Many new sewers are wary of computerised machines, however most are so simple to use and offer so much more than a basic electronic machine. All that differs between a computerised machine and electronic machine is the way that the stitches are selected. Fewer moving parts can mean less mechanical issues too.
