I am paralyzed on the mock wrap t-shirt. I am, therefore, taking a break and have traced a blouse pattern, Simplicity 4586, another "Threads Collection" offering. Old and out of print, but a style I like and, if it fits, has the promise for many variations. I pinned the tissue pieces together and tried them on the dress form and the fit seemed okay. I then compared the pieces to my Bernina My Label shirt pattern. The sleeves and the armscyes are different. Where one area is too little, the corresponding piece is too large and vice versa. The total amount seemed close, so I'm gonna go with it. As you can see, I generously added to the side seams.
I also attempted to fit the pattern on me, but I couldn't make a good assessment as the pins holding the pieces together stabbed me! You heard my screams, didn't you? I am sure the pins are exacting revenge because I tried out the "rocks for pattern weights" idea. By the way, it worked great! Why I haven't done this before, I do not know. Such a simple thing. No problems with the pieces slipping around. I put several of them in a little basket, so they would be handy. They are heavy and long term, will break that little basket. I need to poke around here and find something sturdy to put them in.
