Comments – “A Stitch in Time”
Here are a few of the responses to “A Stitch in Time” left in the comments book:
I love the concept of this and recognise the need to have these conversations. Thank you for blending science and religeon/spirituality [sic].
Excellent, Outstanding. No other words to say.
I absolutely love yarn.
I wish we’d had something like this at school. I’d have learned a lot more. Knitting is so visual and much more accessible than the ball and stick kit we had in chemistry.
This display is great! I never could have imagined Lent can be so modern if not this display! Thank you!
I glad people seem to be engaging with the exhibition, and that it is provoking thought and conversations. I hope it continues!

Timings of “A Stitch in Time”
“A Stitch in Time” will be exhibited at Bristol Cathedral from 6th March to 6th April as part of its Lent carbon challenge. The Cathedral says:
Each Lent churches in the Diocese of Bristol set themselves an environmental challenge. This year the challenge is all about saving and conserving water and we have developed a free exhibition to explore the issues further. Bishop Mike and BIshop Lee recently went on a trip to Uganda, which is linked with the Diocese of Bristol, and saw at first hand the issues communities face with gathering and managing their water supplies. Local priest, Rev Chris Dobson, who was travelling with Bishop Mike took photographs of the local community and we are also featuring photographs which show the beauty of water as a natural resource. Alongside that we also have a ‘Particulart’ exhibition entitled ‘A stitch in time’ which helps people visualise the carbon particles in our environment through a display of knitted particles, which has been developed by Clare Bryden. We are very grateful to both Chris and Clare for helping us with this exhibition. Admission is free – come and visit the south choir aisle.
