A beach/picnic type blanket?

Recover your ironing board. Those fabrics are so pretty, I'd like to see them very day!
A hamper, appliance covers, bed runner, sewing machine cover, wallet, chair caddy, wall hanging, and then of course the window treatment.
You could probably get TONS more ideas off of Pinterest.

Since you have already preshrunk the fabrics, they appear to be in good shape. I'd surely use them in a quilt. They are lovely prints. Can't wait to see what you decide to make.

Decorator pillows, curtains, covering smaller items like footstools, handbags, totes, especially totes for grocery shopping.
Bet you'll think of lots of things along with the aforementioned, quilts. Have fun with the fabric!

Oh my gosh, so many great ideas! Thank you all, I can't wait to get started.

The fabrics are very well coordinated. I would use for a quilt also. But I can also see it as a slipcover for a simple chair (i.e., a simple bedroom slipper chair). You could use one for the back, one on the right arm, another on the left, another for the seat, another for the flip seat, all around the outside, etc. It would become a real conversation piece. Or placemats, table runner, throw pillows or even a jacket using a different fabric for each component (serge your seams and just line the sleeves). You error should provide some awesome prizes!! Please keep posted on your decision and finished project.

Since you have discovered that they are cotton, and washable, why not use them in a quilt. I have used decorator fabrics in quilts, so I say go for it. Otherwise, you could make pillows, cushions, of course bags of all kinds, the uses are endless. Just stretch your imagination and you should come up with beautiful results, especially with those fabrics.

I thought of this idea too. I need to use some to cover some cushions on my porch chairs.

They also make pretty pillow s
