I think the best way to give credit is mentioning the name of the creator wich is u/Aggravating_Risk_882 on reddit. I hope you asked them for permission to share their pattern.
@Credits I found the original pixel art as a cross stitching pattern another fan made and altered it for this site. You can find the images I referenced on a Reddit post called 'Idia from Phantom Bride event patch', or by doing a quick Google search.
