I don't think we ever used a sewing-machine to do the garters - just a 1/2" overlap, oversewn round the edges, took all of 5 minutes by hand... even for me! I wish I had the energy to do 3-3.5 miles each day! I'm trying to get fit, but right now I'm in a soggy puddle on the sofa having walked <2 km yesterday! Must get up and go to Lidl (all of 150 metres away), but can't find the energy....
