I've been wanting to make some of these but since I have coasters, I never made them for myself. And I've never really had an occasion to make them for someone else, until now.
I bought a fat quarter pack from Joann's awhile back and used that. The fabric is from the brand "Jersey Girls." At least, that's what some of the selvages said. I'm pretty sure that one of them is an Alexander Henry fabric (no selvage on that one), but I could be wrong.
I got the idea from this book: Last- Minute Patchwork and Quilted Gifts. It is such a fun book! I bought it when I first started sewing, thinking it would get me in the swing of things and give me plenty of stuff to practice on. I've only made a few things from it, but it has so many great gift ideas in it.
And everything is organized by how much time it should take you to finish- from under 2 hours to over 12 hour projects. If you don't have many sewing related gift idea books around, this is definitely one I recommend. It has great ideas for using up your stash and those scraps you can't bear to throw away (or is that just me?).
