I too shop at the place where nothing is over a $1 and have found zip closed bags in several sizes there. From one gallon to big enough to hold a finished project. I have found them to be a nice heavy weight plastic as well.

I use the 1 or 2 gallon ziplock bags. I prefer the 2 gallon, because it can hold more fabric. I get them at Target.

The small 12.5" x 14.5" bags are now $2.00 each. http://www.quiltinaday.com/shoponline/gift/34710

I use $1. plastic shoe boxes to store pre-cut squares, triangles, jelly rolls, charm packs and small scraps separated by color. Smaller bags within other plastic shoe boxes are used to sort 4 patches or HSTs by size. Uncovered plastic shoe boxes within a large drawer are compartments labeled as to press, to trim, and file. Pattern, fabric and usual work in progress fit in the flat scrap-booking type hinged plastic boxes used by Judy in Phoenix, AZ. The exception would be using a large sweater box if working on one of Bonnie Hunter's mystery quilts because I corral so many colors. :-) Confession: UFOs or almost finished WIP can be downsized to Rubbermaid take-a-longs about size of 9x13 cake pan.

No wonder DH says I have containers for everything or was that everything goes in some type of container! He's <3 right! :-)

I like to use various size zip bags for projects or portions of projects in progress. I also have some rectangular plastic baskets of different sizes that work well for holding folded fabric set aside for use in a specific future project. This allows the fabric to still be visible so I don't wonder "whatever happened to that pinecone fabric I know I had" yet obviously set aside for that project.

I use old pillowcases

I buy storage bags from the Dollar Store. They have a ziplock closure and a handle and the large and X-large are great for holding all the fabrics. And best of all - you get 3 for a dollar!

These look neat! I like $1 ziploc xxl bags from the dollar store, but this is a close second. Wonder how shipping is...

I have some from Eleanor Burns that I like really well. She has them on sale once in a while and that's when I get them. I get her emails.

Do any of you use Schwans? I asked my Schwans guy for some extra bags. They are really big and he gave me about 10 of them! Nice! Plus I keep whatever bags my food comes in from Schwans as well

plastic containers
 

I used to use Ziploc bags and still do but have trouble finding the 2 gallon size.
I stacked them up but they started sliding on each other so I go to the container store when there is a sale
and buy the sweater size clear plastic storage bin for $5. That holds one quilt's fabrics [queen] or lots of
ziploc bags of smaller fabric collections for runners, etc. I can see that I need to visit the Dollar Store for
cheaper boxes, but these don't break and are stackable. They are also repurposable to store clothing or
other household goods.

I use project boxes that I purchased from Costco for 14.99 for 5 of them...

I have 5 cabinets in my sewing room (15" deep BILLY bookshelves from Ikea, with doors). I bought extra glass shelves for them, and so in one cabinet, about half of it is glass shelves. I have some square trays (also from IKEA); two of them fit neatly on each shelf. I use the trays to stack my WIP onto, and then those sit on the glass shelves. The glass helps me be able to see what's going on; and when I want to work on something I just pull that tray out and it's all right there. For smaller projects I can even stack the trays 2 or 3 high on my shelves. (Larger projects mound up too high for that.) If it's a really large quilt with a lot of little pieces sometimes I have to use 2 trays for awhile...just depends on what's going on.

I use the zip lock bags a lot, all sizes, and the idea of using a paper plate to organize within the bag is a great idea. Thanks to you all who recommend the dollar-type stores for those bags which don't have to be the expensive freezer ones.
I've also used the large size plastic container that pre-washed salad comes in, nice and deep and easily stored. ..not for long-term storage of fabric, but to help organize "stuff."

I am about easy and inexpensive. I tie fabric bundles along with patterns with salvage strips and stack on a shelf. Once blocks are cut, I lay them out on pieces of fabric backed vinyl tablecloth cut to accommodate the size of the unfinished block. This works especially well for sampler blocks and applique. For chain piecing I place cut pieces in shallow plastic food containers. Either way you can place them near your machine when you are ready to sew. Can even use them as leaders/enders Bonnie Hunter style.

Thanks for the tip to order some project bags from Eleanor Burns site. They are currently on sale and I just bought some!

me too - The large Quilt in a Day project bags are what I like. I bought my first set when they were 2.50 each and my last set when they were $3 each. I like because they have handles - for when I go to my quilt group.

I've used the Ziploc bags but found they slip and slide around my closet. Now I use clear project boxes I buy at Craft Warehouse. They are usually 3/$10. They are clear so I can see what's inside, I can label them too. The stack neatly on top of each other.
