Inspiration for a non crafter please!

Recently, I watched a woman 'designing' a set of 3 different sized white plastic plant pots in 3 colours using Poscas. One was a complicated design, one was a motif from the first one and the 3rd was covered in one of the colours with a different motif from 1st on it.
Craft is a lovely idea because you're sharing but with minimal language. Silences are not a problem. Seeds and a bag of compost would be good for travelling home.
If you do something similar, check your Poscas are in good condition and you've enough.
Thanks for reminding me. I'm going to have a go myself today.

I think I'm maybe confused.
Is your mum French and visiting with a friend?

I’m not sure you need to bother either if the lady has some English I am sure you will manage two hours or so what with lunch and two hopefully chatty grandchildren. A lot of crafts need nimble fingers. We have French relatives who speak no English and there is lots of smiling and pointing
Photos are a good idea

Not soil based.

If she's only here for a very short time I'd not want to start a craft, personally.
I think you are maybe worrying unnecessarily as we all holiday where we have little language.

I'd probably find some photos she would be interested in.
You and your life, your children and theirs, your grandchildren.

You could copy a few of them for a gift?

You will be occupied with eating for a chunk of the visit.
Will they want to craft?

I wouldn't necessarily recommend beads - fiddly if you aren't very nimble.

How old are we talking?
What sort of person is she?
What does she like...

Would you have lunch at home or go out?

Thanks churchview
The beads are a nice idea too.

Your idea sounds lovely.
Other ideas - beading? You could buy some elastic/thread and some beads then everyone will have a bracelet or necklace to take home to remember the day. Collage might be another idea.
