Glass pens for 6 year old?

What about coloured Sharpies.
Not quite the same as paint obviously but might be safer and easier to manage.

Search for "glass pens" on Amazon, there are loads.
Like a felt tip pen, but acrylic not ink.
I had some last year and we did rock painting.

Thanks both

Nail art tools are good for this kind of thing, good for decorating small spaces, getting into corners and cheap to buy. Squeeze small amounts of paint onto an old saucer and dip. Supervision required but very good for practising hand-eye cordination.

We used to buy glass paints in little ink-type bottles - you probably want them to be transparent so that the sun shines through. Lots of acrylic paints are opaque.

I'd be wary of fumes using any kind of solvent on plastic though.
I've no idea about the content of nail art products mentioned above so may be speaking rubbish here!

You could always mix pva glue with paint/food colours as we used to to make suncatchers on the stiff-ish plastic from packaging.

We used to mix up a black and draw an outline one day then when it was dry (usually the next day) you can paint between the lines using an ordinary small paintbrush.

You can either make a little hole and hang up the design or peel off the dried design from the plastic backing and it will stick directly onto a window as a piece of cling-film might.

My grandchildren have had these and with little pots of paint that they painted on with a small paintbrush. It worked fine.

I've used overhead projector pens with children. You can also use the plastic paper. Use colouring books to trace pictures.

Posca pens?

Does it bother him? My GC doesn’t worry about the end result as long as no one has helped. I think a few splodges might give an interesting effect. If he does get frustrated, how about a fine paintbrush to spread the paint? Thanks too for a good craft idea to suit GC.

Baker Ross Creativity pack of Suncatcher Paint pens. £7.95 on Amazon with next day delivery. Think they’ll be ideal 😊!

Yes use Sharpies I think !

Squeeze the paint onto a small plate or palette and use a fine ,firm brush.

My 6 year old granddaughter used nail varnish but I only had two colours!

I was imagining a six year old in a play pen made of glass, and I thought of a few disadvantages

I used to paint on glass when I was a wee girl, I used watercolours which are fairly transparent.

At the end of the day, all these intricate crafty things can’t easily be mastered by 6 year olds. I use activities like this as a well supervised hour of fun. But keep a brush too to help spread the paint. They are lovely and I have them up on their bedroom window for when they stay. It’s the same with threading beads and stitching pictures. They WANT to do it, but need a hand. I dread the day when they no longer want to - they will have the skill level then but no interest ( I have 5 under 8sDGC)

I bought some acrylic paint pens off Amazon and they are fabulous. bit like a felt pen but paint. I've not tried them on glass but it says on the packet you can use them on that. Used on wood very successfully and very easy
