A Cumbrian mum-of-three has now been missing for 40 days.
Mary Monkman, of Kendal, was last seen on June 16 in Ayrshire.
She had left her home earlier that day and was spotted in the afternoon driving near Loch Doon.
Her family and friends have no idea where she is and are desperate for her to make contact.
The businesswoman runs the successful Lakeland Artisan brand with her husband Geoff.
He said he just wanted her to make contact with someone to let them know she was okay.
Several appeals have been made both in Cumbria and Scotland, but her family are no nearer to finding out where she is.
Mrs Monkman, 49, has been described as a popular and optimistic woman.
Geoff said: ““I have to hope that Mary is out there reading this, somewhere. Mary, if you see this, just know that we love and miss you terribly. Please let someone, anyone, know that you’re okay.”
He has spent time in the Loch Doon area handing out flyers in the search for his wife.
Police in Scotland are continuing their search for Mrs Monkman. Her brother, Silas Denyer said it may be possible that she has travelled from the Loch Doon area and could be further south.
She is around 5ft 9in with shoulder length curly hair that had recently been dyed purple.
She was wearing a sleeveless floral top and leggings and lightweight shoes and was carrying a distinctive Deuter Step Out 12 rucksack in mint/petrol.
Anyone with information is asked to call Ayrshire police on 101.
