I'm confused by these machines. Other than the colour and decals, they look exactly the same.
There are 15 stitches shown on the blue one (well, 14 and a buttonhole, same as the red). The knobs for setting stitch length are the same, so I can't imagine Janome engineered different feed systems for the two of them to create different maximum stitch lengths.
Do you have any documentation available for them, to confirm that the features are actually different? If they're the same, then people can choose based on colour, knowing that they are getting the same machine either way. Even giving the model numbers would help; I wasn't able to find these machines on the Janome website.
Thanks in advance!
