Do you swap blocks? and if not, why? My question is one of pure curiosity. - I don't any longer.
When I first started seeking fellow quilters on the web I enthusiastically joined a number of swaps of various sorts: FQ's, charms, friendship stars, 12 months, rowXrow, etc. Now, I find that I'm much less likely to engage in certain kinds of swaps, if any. These are usually the ones that require the use of certain colors or styles (30's repro for example) that change for each participant, or extend over long periods of time (round robins) where you have to rely on the persons preceding you to get your bit out in time. And I've found that with all the block or row swaps I've done, I've yet to assemble a single top from any of them and I'm at a loss to explain why except that none of them move me to want to finish them, even for charity. I donated a number of them to the block orphanage.
After much thought, I've concluded that the annoyance of keeping track of what I send and receive is the primary reason for me, followed closely by picky participants/hostesses who want not only a particular color but a style that I don't have in my stash or a theme fabric that is just not available for one reason or another requiring me to run around trying to find something suitable.
How about the rest of you non-swappers out there?
