A grandmother was forced to write an apology note to her granddaughter’s teacher when the youngster used a permanent marker to draw on bushy eyebrows.

Louisa Jackson, 59, arranged to take her six-year-old granddaughter Phoebe to school as a favor to her daughter Amy.

The grandmother of four asked Phoebe to brush her teeth before the couple left home for school.

But when the girl came down the stairs, she sported a pair of giant Sharpie “like Groucho Marx” eyebrows.

Louisa spent 10 minutes trying to clean them, only to remove the worst of the ink with baby oil and cotton wool.

But Phoebe still had a “dirty” stain on her face, so Louisa was forced to write a note to her school explaining what had happened.

She’s now committed to keeping the permanent markers hidden for the future – after Phoebe also painted herself red in an attempt to look like the crab from The Little Mermaid.

Louisa, from Bexley, Kent, said: “When I looked at her I just thought she looked like Groucho Marx.

“When I was little, I went to see the Saturday morning photos and they showed the Marx Brothers movies.

“I thought it was Amy’s mascara to start with, which is easy to remove. So I just took baby wipes and wiped it off and nothing happened.

“I said to Phoebe ‘why did you put makeup on mom?’ and she said ‘it’s not, it’s a pen’.

“I realized it was a permanent marker so it wasn’t moving.

“I rubbed them for ten minutes, then I poured baby oil on cotton wool and that’s when it started to peel off, but it was still pretty dark.

“She loves makeup and obviously decided she wanted eyebrows that day.”

After running against the clock to get the pen and Phoebe out of class on time, Louisa also quickly wrote up an explanatory note for her teacher and handed it over.

Louisa said: “Phoebe must have gone to school with a stain on her face so I put a note in her binder.

“I wrote ‘I’m sorry if Phoebe’s face looks a little dirty, but she drew up some eyebrows with a permanent marker and I did my best to take it off.

“We will certainly make sure that permanent markers are out of his reach in the future.

“As she gets older she can achieve more things and you don’t realize what she can achieve until something like this happens.”

Three years ago, Phoebe covered herself in a red felt hat in an attempt to transform into Sebastian from The Little Mermaid.

Louisa said: “When she was three years old, she colored herself red after watching The Little Mermaid.

“She said ‘look I’m a crab’, which came off in the tub because it was a regular children’s felt tip pen.”

Sharing her status as a permanent marker on Facebook, Louisa wrote, “Grandma fails!

“My only mission was [to] make her stay overnight, get her to school on time on Monday morning.

“Mission over but I haven’t told mum yet that I sent her to brush her teeth and she went downstairs [with] eyebrow permanent markers.

“I got most of it out with wipes and baby oil, but had to put a note for the teacher in her binder because she still looks a bit like Groucho Marx.”

Social media users were tickled by the image and joked that they had seen eyebrows like this on women in the evening.

One said: “To be honest, I’ve seen real adults draw their eyebrows like that and go out on a Saturday night.”

Another wrote: “Better than some of the eyebrows I see today.”
