So time to revamp this rocking chair, because summer is coming!
After removing the remains of the seat, treatment with a steel brush, some sanding and a little bit of glue in the joints I gave it a three layer coating of oil.
Then the difficult part came; the weaving of a new seat. I had a disposed and incomplete insect-screen with a nice colorful look kept for this purpose. I thought it wouldn't be hard to try the same technique as was used with the rush on the old seat. I was wrong, because of the trapezium form of the frame and the width of the ribbons that didn't work. I tried it according some instructions found in some old books I have (I've got quite a big collection of how-to books and other instructional stuff) and instructions found on the internet.
Then I was inspired by this Instructable (thank you Katvanlew!) and decided to just weave it in some sort of herringbone pattern (as in this video on youtube, however I made my own variation). I'm quite pleased with the results so, let those pleasant warm and long summer-evenings come for some rocking rest!
