We used to do jigsaws fairly regularly but we got out of the habit a few years ago. We have one of those 'jigsaw savers' which is a bit like a giant portfolio holder but it keeps all the pieces in place so you can move the jigsaw around while it's half finished. I recently retrieved it from the front room because I remembered that we were part-way through a jigsaw but couldn't remember which one it was.
I think we originally started it a couple of years ago and we might have temporarily given up because we were finding it difficult. There are a lot of pieces with similar colours and there are very few hard edges, making it very tricky to find the exact piece you need.
We continued with the jigsaw about a week ago and finally finished it tonight, doing a couple of hours here and there. We need to tackle a simple relaxing less frustrating jigsaw next.
