The Basic Conical Torso Block (Part 2)

Marking Changes

Remove your fitted block.

The Center Front adjustment makes an angle between the original Center Front line and the fitting line drawn in. We need to bisect that angle. First, draw a tick on the edge of the bodice at the midpoint between these two lines.

Mark the midpoint between the other ends of these front lines.  (Since my ends converge, this is already done.)  Connect these midpoints.  This is the new Center Front line.

Mark an arch that connects the ticks marking the waistline adjustment in the back.  This is the new back waistline level.

Finishing the Block

Place the poster board block on a large sheet of paper.

Trace around, being careful to mark all of the shaping lines.  When you come to the strap adjustments, make a neat curve in place of the chunky angle folded in to the strap.

Connect the shaping line marks, and label the Side, Center Front, and Center Back lines.  Label the block.

Viola!  Cello!  You’re done!  As a best practice, any time you make a block (or pattern) you should label the block with what it is, who it’s for, and the date it was drafted.  I’ve labelled beneath the block for readability here, but in future demos you’ll see a block labelled “Basic Conic Block, Brenda, 06/10”.  The date is most important when drafting for humans, who tend to change dimension over time.  (I have something around 62 patterns for the same basic ren corset for myself, for example, because of my little yo-yo diet habit.)

As you go forward, it’s always easier to re-check the fit of a block (or re-draft the block) than to make a fully boned corset and then have to alter it.  Poster board is cheap, and really fast for mock-up purposes.  A fully boned corset in a lovely silk-linen blend, hand-bound with silk bias, which then flat-out refused to close is expensive and really annoying to alter…..

Possible Problems

if… try…
Your Armscye ends up above your bustline…. Recheck your Nape->Bust, Nape->Waist measurements. Make sure you’ve taken them out to the level of the bust, rather than flat across the body. If you have taken the measurements correctly, don’t worry about it. Just draw the armscye up on the side line.
When you mark your Center Front adjustment, you need to add at the waist and remove at the bust, resulting in a big ol’ X between the Center Front and Adjustment lines…. Don’t worry – this is completely normal. Mark the midpoints, top and bottom, and draw in the New Center Front line.

This list will be updated based on questions posted in the comments section….

      You can find larger poster board than that at most art stores – (including Hobby Lobby, Blick, Michaels, etc) and any place that caters to students (walgreens, target, kmart, walmart-even-thought-I’m-still-boycotting), and often also at JoAnn’s.

      Hope that helps….
