kevlar canoe

Hello guys,
I need technical advice from people having experience working with kevlar.
I plan to make kevlar canoe myself. The plan is for 18’ canoe 3 or 4 layers with vacuum epoxy infusion.
But I recently got over pretty inexpensive kevlar sheets 3 ft x 5 yd pieces.
Which means it will be made from many pieces.
How is from you experience, how much it may affect hull strength?
Is it worth to consider making it from pieces or better not to take a risk and go with one piece per layer?
Thank you for your time.
