Help me finish a quilt and cross stitch

I would like to finish a pillow case cross stitch my granny started. I inherited it years ago and would love to finish it and put it on display. It is very sentimental and would be a great way to honor her legacy. Can you help me finish it?! I’m rusty on cross-stitching. Also, I have a quilt that needs completing. Same problem—I kept it and never finished it, I need some expertise and motivation. The pieces are stitched in a pattern but it needs to be finished off—backing, edging, etc. Can you help me with one or both? I’ll get all the supplies, I just need guidance and execution. Thanks for considering!
