Cut. Sew. Press. Transform your stash into a concrete jungle of creativity!
Several abbreviations are used on this page. They are:
A 1/4" SA is used in this tutorial.
Highlighted in yellow, pressing instructions are easy to spot.
To press, first press the patches in the closed position as they came off your sewing machine. This sets the seam, melding the fibers of the threads into the fibers of the fabric.
Then press the SA to the dark unless otherwise noted.
Paper Pieced Seams
For strong, secure seams:
Apply this to every paper pieced seam. The extra stitches help prevent seams from coming undone when removing the paper.
To download the pattern, use the most current version of Adobe.
For accurate results, on Adobe's Print Menu page, under 'Page Size and Handling' set 'Custom Scale' to 100%. Then print.

After printing, use the 1" square graphic on the printed page(s) to double check that your patterns printed at the correct size.
Then cut out the required number of patterns from your copies. A rough cut is good enough—an 1/8"-1/4"-ish away from the outside dashed square.

Let's get the gluing out of the way.
Use just a dab of Elmer's Washable Glue Stick to hold the first patch in each unit in position on the pattern—wrong side of the patch to the unprinted side of the pattern. Use the dashed guidelines for foolproof placement.
We need to make a few adjustments to our sewing machine settings to paper piece.
Make 4
With RST, match the long edge of BitA-2 to that of BitA-1.
With such a light background, I want to make sure that the darker pink doesn't shadow through the white once the block is finished. For extra insurance, nudge the lighter BitA-2 a few threads past the edge of the darker pink patch. (blue arrow)
If you're using a darker background fabric, you needn't do this.
Sew the seam starting and ending past the outside edges of the BitA.
Press.
With RST, match the short edge of BitA-3 to BitA-1. (The lighter BitA-4 is offset again, blue arrow).
Stitch.
Press.
Time for a quick trim to create the exact placement for BitA-5.
At the cutting mat, pattern side up, match the edge of the ruler with the solid line between BitA-3/4 and BitA-5. Use your thumbnail to crease the pattern along the line.
Fold the pattern over on the line. Position the 1/4" ruler mark over the folded edge. (blue arrow)
Use your rotary cutter to trim away the excess.
Back at your trusty sewing machine, match the long bias edge of BitA-5 to BitA-3/4.
Sew the seam. Since it runs from outside edge to outside edge, this seam is a candidate for chain piecing.
Chain piecing? In paper piecing?
Yep! There sure is!
Set the BitAs aside. We'll trim all the units right before removing the paper pattern.
Make 4
With RST, match the long bias edge of a Sky to one for the short sides of the Goose.
Here is the seam after sewing.
Press.
With RST, add the second Sky.
Press.
Add these to the four BitAs already set aside.
Make 1
Paper piecing this unit tames all the bias edges it contains and leaves you with a unit just the right size. It's the only way I recommend making this patch.
With RST, match the long edge of #2 with one side of #1.
Remember: Sew a generous 1/4" seam (see General Instructions for details).
Press.
Fingerpress the #2 open and out of the way and add the second #2 to the opposite side in the same manner.
Give the unit a good pressing at the iron.
Repeat for the second pair of #2s. With scissors, trim away the dog ears.
Press.
To create the perfect placement for the #3 patches, place your Center unit on the cutting mat, paper side up. Pull the paper away from the stitches enough so that you can fold the pattern back on the solid line.
Line up the edge of your ruler with the solid line between #2 and #3 and crease the pattern with your fingernail.
Fold the pattern back on itself on the line. Position the 1/4" mark with the folded edge (blue arrow) and trim away the excess, leaving behind a 1/4" seam allowance. Repeat for each side of the #2 patches.
After trimming, your unit looks something like this:
Let's start the round of #3 triangles.
With RST, align the long edge of a #3 with the trimmed edge.
This #3 is much lighter than the #2, so it's nudged a few threads past #2 (blue arrow) to prevent shadowing of the darker fabric through the lighter one.
Sew the seam. Repeat for the opposite #3, pressing afterward.
Repeat the process for the second pair of #3s.
Here you can see those dog ears after the third #3 is added.
Trim away the excess fabric, leaving behind a perfect 1/4" seam, just like we did after all the #2s were stitched.
Continue on in this same manner for the #4s and #5s.
Return your sewing machine to your everyday settings.
We stitch the remainder of the block with traditional techniques.
Install your favorite quarter inch presser foot. Adjust the needle position if needed. Return to your normal piecing stitch length.
This process is the same no matter which unit it is. With the unit on the cutting mat, paper side up, position the 1/4" mark on your ruler with one of the solid outside lines.
Trim away the excess.
Turn the unit a quarter turn and repeat the process. Again, and again, until all sides of all the pieced units are trimmed.
It takes our patches from looking like a hot mess to perfection.
Remove all the paper from your Center, BitAs and FG. Patches are calculated to create units with straight of grain on the outside edges. The paper no longer serves a purpose, and…
…it's a pain to pull paper out of a 1/4" seam allowance.
Don't make extra work for yourself. Remove it now.
Time to lay out our pieced units into the Philadelphia Pavement block design. The FG point outward from each side of the block. BitAs are in the corners with the background patches on the outside edges.
Stitch the units into rows. The only thing to worry about matching at this point are the edges of the units.
SAs are pressed toward the FG.
Sew the rows together. I did use pins to help match and hold the points of the FG around the Center unit.
IBC's super fine pins are my tool of choice for matching points.

These last two SAs are pressed out from the center.
Remember, you've got this! Take it one step at a time, and soon you'll be walking on your very own Philadelphia Pavement! 🏙️
We've covered cutting, paper piecing, and assembly techniques for this classic design. Remember, practice makes a confident quilter—each block you make will improve your skills.
