well, shirl, here's the thing ... you don't really need to worry about lack of confidence or anything else when deciding whether or not to tackle one of the blocks we've picked for each other to try.
you can take as long as you need to put it together ... or take it apart and put it together again ... and again ...
we will sympathize with your trials if you tell us about them, and rejoice with you when you finally get the best of it. and if you never do ... and never say ... we'll never know the difference. :wink:
dont' let fear stand in your way. :P
