We´ve got this good, old bike that serves as the family grocery shopping bike. It´s been in the family for a slong as I can remember, and it´s startingt to look rusty and worn. The latter can be charming, but in this case a makeover is required. First off is a seat cover for rainy days. You can always use a plastic bag, but with this tailor made cover you can look smart on a sunny day as well.

What we used
Waxed fabric/waterresistant fabric
Elastics
Safety pin

How we did it
Maesure the approximate surface of the seat and draw it on to the fabric. Add 1 cm for the seams. Measure the tallest point of the seat as well, and add 3-4 cm to it. At last measure the circumference and add a couple of cm for the seams. Make one seat shaped piece of fabric and one long thin one.
Use pins to attatch the.
Cut some incertions where it´s curvy to make the sewing easier and prettier.

Sew around. Then sew the short ends of the long fabric together.
Make a 1,5 cm fold all around the lower end of the seat cover. Sew along it, but leave a small whole to pur the elastic through.

That´s it. Tighten the elastic as much as you need to be able to take the cover on and off the seat. Take it for a test drive!
