The 52-year-old’s obsession with hit series Twilight has led to her getting a copy of the New Moon film poster emblazoned across her back, portraits of Edward Cullen on both ribs and the Cullen crest splashed across her breastbone.
'When [my] body's completely covered, we're looking at between £17,000 and £25,000.'
'I've had about 91 hours of tattooing now and it's costing a small fortune,' explains Reading-based Cathy, who plans to get a full bodysuit tattoed.
'I've forked out just under £8,500 and by the time I'm finished, when [my] body's completely covered, we're looking at between £17,000 and £25,000.'
The Morrisons baker admits that it’s more than her obsession with main character Robert Pattinson that has spurred her tattooing spree.
For Cathy the etchings mark how far she has come since she started her body project in 2009, when she was 6 stone heavier and a size 24.
Speaking about how the shock of losing her mother caused her to comfort eat, Cathy revealed:
'That's when I started going really hell for leather doing what I wanted and abusing my body.’
'I'd get another tattoo and it'd just give me something to focus on'
'I was sitting down, overeating, just vegetating all the time. I was ashamed of myself and what I looked like.
'When my friend gave me the first book and I got well and truly hooked on it, it kind of focused me. Of course, then I got the music, the soundtracks to all of the movies, so I got them out, I'd exercise to them and I'd be watching a DVD and I'd just be exercising in front of them.
'And then I'd get another tattoo and it'd just give me something to focus on. I've lost six stone and that's what did it.
'It's a permanent reminder and a reward to me for getting my life back on track to what it should be.'
