I had some small ones (made into hst's) and used them as borders on a patriotic quilt , but had added corners to them to make them larger. square in a square.
also used some up from snow ball blocks and used them in the inner border on that quilt. did sort of a zig zag with them.

Depends on the size. Most get a decent burial. froggyintexas

I love the way you have used the triangles of different sizes, Colorfulom

I just made a quilt and had a lot of HST left and used them in the border.

Thanks for all the suggestions. Great bag and quilt!!!! Now to go through and see how many I have that are the same size. Another project in the making.

Make a Lady of the Lake quilt out of the leftovers. Makes a great scrappy quilt.

All great ideas. Thanks

Depending on the size and what pattern I'm working on I've used them on the border to add a little extra character. Here's a couple I've used the cut-offs on........... Otherwise they get thrown into a small tote I keep them in until I find a use. Maybe make a pillow to go with the quilt you're working on.

I keep all leftover blocks and pieces....the blocks are saved until I have enought to make a VERY scrappy and wild quilt top (grandkids love em)....all pieces get tossed into a tub until there is enough to mess with, then all get cut down into usable size squares or strips.

Bonnie Hunter has so many pattern that use small leftover triangles and squares. Check her website and her several books
