I've frequented Pink Castle Fabrics multiple times in the past. Brenda has a great selection and variety of fabrics. I even had the chance to meet her for the first time at Market last month. It's fun to finally put faces with names.
Along with the great selection over at Pink Castle, there are a few particular things about her shop that I love. First off, I love the Stash Builder's section of Brenda's shop. You can search for great blenders by color. I have a post coming up later this week about blenders because I use them a lot, particularly in the color wheel projects I've done and have in mind for the future. Simply search for aqua, lime, grey, red, etc when looking for a particular color.
Next up I love the Blogger's Bundles section. Multiple bloggers have selected bundles for the shop. It gives such a great variety for quilters looking for something different when it's hard to break out of a line. I have my color wheel stash bundle in there for those looking to increase their variety of FQs in all 12 main colors (sold out at the moment). Right now I'm also really liking this bundle by Maureen Cracknell:
Finally, Brenda has an amazing selection of solids. She carries FreeSpirit, Cotton Couture, Bella, Kona, Dear Stella, and more. It's easy to search solids by color as well as manufacturer.
Check out their selection. Don't forget to follow Pink Castle on Twitter as well as their blog. Brenda frequently posts sales that are too good to miss!
