My "go-to" to search for fabric is
www.quiltshops.com - their search engine is excellent and searches through the inventory of over 100 stores.
I tried to copy and paste the results of searching for the fabric you're looking for by typing the name of the P&B line in the search engine and it came up with 56 items; for the Laura Gunn fabric, it had 207 items! When I pasted the links of the search in this message, it wouldn't connect back to the correct pages, so my idea didn't work.
If you've never visited quiltshops.com before, get your favorite hot or cold beverage, get settled in your most comfortable clothes and chair and be prepared to be online for A LONG TIME! You may be there awhile!!
