I was trying really hard to think if I had anything that fit that description in my wardrobe. Sure, I have a blue top but it has elephants on it! Not very appropriate!
And, yes, I have a white blouse but it has pink pussycat buttons on it. Not very appropriate either!
So, what did I do? I made a new blouse of course! The best part about buying polycotton sheets when they're on sale is that I usually have something I can use to back a quilt or, in this case, make a sea-coloured blouse!
Not only did our conductor want the ladies in sea-coloured blouses but she also wanted the men to wear sea-coloured bow ties. Now, I don't know about where you live but there's a definite shortage of shops around these here parts which sell bow ties never mind sea-coloured bow ties. So, after I'd made my own blouse, I decided I'd make our men some bow ties. I've made bow ties for them before ...
... so I knew exactly what I was doing. Thankfully!
See, keeping scraps comes in handy yet again! :oD
