1. Do you have a verified valid robots.txt that Google can read?
2. Does your verified valid robots.txt point to a verified valid sitemap or sitemap index?
3. Did your submit your verified valid sitemap or sitemap index to Google Webmaster Tools?
Based on the responses to this, I or someone else might be able to help you further. Good luck to you.
1. Yes, I have that. 2. Yes, I also have that.
3. Here's an actual screenshot of my google webmaster tools for my website:

Remember: We're now closing in on 6 months with Google just not crawling my site whereas other search engines crawl near daily.
1) What is the URL in question.
2) When you click the 'why not' link what does it say?
The other (possibly not relevant) question is whether or not you have any Google advertising or not on your site. I'm not suggesting that there is a 'pay for play' here, what I'm looking at is that when you use 'AdsenseForContent' or (AfC) the only way Google can know what sort of ads would make sense on your page is to crawl them first. If you had AfC ads on your page and Google wasn't crawling them, then that would suggest that your URLs are black listed for some reason. At Blekko our crawler tries to avoid sites that are either patently malicious (they've got known exploits in their pages) or on a list of malware/childporn sites, or have complex page structures that don't involve recursive crawling loops.
What is the URL of your site?
I guessed your sitemap URL since it isn't in your robots.txt. You have every single page listed as being updated hourly. Even if that is true I wouldn't put that in there.
Hmm, if that were the case I'd expect it to show up in the Transparency report though.
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.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#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.
Relying on another company for all your business isn't a sound business strategy. The person in the article put all their eggs in one basket and this is the result.
And so, yes, pretty much everyone is reliant on them to be good stewards of the power they possess. (Whether they are or not is orthogonal to that the quilter in question has a pretty good reason to feel like they aren't.)
If Google is against you, you're done.
How do you suggest a web-based company should counter that and not rely on google for much of their business?
So they open up their browser, type portrait quilts in the address bar, which redirects to a search, and your website is on page 8 despite being an exact match on the search. Game Over.
Seems your other channels are not quite as effective as you thought if google decides to penalise or blacklist your site. If you're off page 1 or 2 you may as well not exist. Of course from Google's point of view, you'll just have to advertise with google, so this doesn't penalise them at all, in fact they are rewarded monetarily for arbitrarily shifting rankings periodically (not that I'm suggesting that they go out of their way to do this, just that the perverse incentive is there).
Personally I find Google is providing results which are less and less useful, with their recent emphasis on monetising search, indifference to fairness, and lack of transparency as to their ranking methods - it certainly seems as if in this case a draconian penalty has been applied, and there is no effective way to appeal or even find out what the judgement against them was (webmasters very often is not helpful). A penalty of a few places would be completely understandable if they don't like this site for whatever reason, a penalty of 8 pages while other spammy results dominate search terms is not.
I've switched to DuckDuckGo for now and it's pretty good. Compare the results for Tipex (a popular brand of correction fluid in Europe) for example:

Google makes software, and no software is perfect. I've been bitten by shitty google services before. My most recent sting was Google Webmaster Tools not showing any Googlebot crawls to me website. My website is very niche and literally 1 of 4 competitors in the same arena.
5 month. 5 MONTHS. and google has yet to crawl my website, even though google analytics shows me stats day in day out.
Why? Google breaks sometimes, and it's incredibly crappy that you can't even reach out to someone to ask what's up.
