Jean Wood, who lives in County Cork, said she was drawn into the project after she saw a post on Facebook.
Although she enjoys sewing and making clothes, she had not done a lot of knitting or crocheting.
“But I do now,” she declared.
Ms Wood made a field hospital near Utah Beach, with an ambulance, tents and injured soldiers.
To make the scene as historically accurate as possible, she looked at photographs and carried out extensive research.
Ms Wood says it is “brilliant” to be a part of something important.
“I love it if the children can be attracted by it and find out just a little bit about what happened in the past so that we don’t forget all the guys that gave their lives and were so brave.”
