Jewish Care resident Simon Davies and his sister Niki Caplan have raised more than £10,000 for the charity by making and selling purple masks.

Their niece, JFS pupil Sophie Coleman, and Ms Caplan’s friend Suzi Slatkin are also involved in the Purplemasks4JC enterprise for which 1,500 washable masks in a range of fabrics have been produced. Buyers make a minimum £5 donation to Jewish Care.

Mr Davies lives at the Rela Goldhill at Otto Schiff care home in Golders Green for those with physical disabilities. His sister is a GP residing in Stanmore.

Raising a five-figure sum in under two months was “incredible”, Ms Caplan said.

“We set a funding target of £1,000 and never thought we’d make it.”

The masks are three-layered and come in six different styles “which chop and change depending on what material we have”.

Her parents have also been involved, cutting the material and delivering the masks around North London in what has become a well-oiled production process.

“We’ve got very slick,” Ms Caplan added. “It takes around seven to eight minutes per mask and we are sewing in every spare moment we get.”

Although most of the orders are from within the Jewish community, “the word is spreading”.

There had been a rush of business after the government declared that face coverings would be compulsory in shops. Purchasers were happy to support a charitable cause as “other fundraising opportunities aren’t available”.

Paying tribute, Jewish Care’s Adam Overlander-Kaye thanked the quartet for “their hard work in reaching this amazing milestone”.
