Some things that may explain things: According to ahrefs, the number of referring pages (a big factor search results) dropped from about 22k pages to well under 1k over the course of 2 months starting at the end of march (source: https://ahrefs.com/site-explorer/overview/subdomains/www.portraitquilts.com https://ahrefs.com/site-explorer/overview/subdomains/www.por...). Additionally, it seems the site does show up in Google search results on the 10th page (https://encrypted.google.com/search?hl=en&q=photo%20quilts#hl=en&q=photo+quilts&start=90 https://encrypted.google.com/search?hl=en&q=photo%20quilts#h...). I'll be honest, I don't understand what exactly that means, but it seems to have happened at around the same timeframe that you're referring to (5 or 6 months ago), so I'm going to bet it's a factor. Hope you figure it out - the whole search engine algorithm thing is really complex. But, honestly, I don't believe that Google just stopped working for a single domain. The more likely scenario is that something you/your sister is unaware of changed and had a large negative result.
