Getting outer circle to lie flat

[Lorraine G.]

I attempted to put the upper road on my circle of houses for Block 5 and although it fit around the circle, it is absolutely not flat.(it looks too small) Can you please tell me what the measurement of both the upper road and the circumference? other thoughts about what I might have done wrong and how to fix it? Thanks so much

I had a terrible time matching the circles and having a flat result.I eventually had to to do it this way:
*make sure outer “frame” is flat and tape or pin it to a flat surface.
*Baste the seam allowance down all the way around the inner circle.
* Lay the inner circle on top of the outer circle, lining up NSEW points where you want them.
*Then carefully pin the circles together, being sure you have an adequate seam allowance on the outer circle.
*Use an erasable marker on the outer circle to indicate where the circular seam should go. I also marked where the road seams should align with the outer row of buildings. Obviously I had not been totally successful creating accurate seam allowances…my outer buildings are a mite shorter than designed as I had 1/8 to 1/4 inch larger seam allowance on the tall building circle. Unless you hold a ruler to it, you can’t tell.
*Take the pins and basting out and pin together with the right sides together, matching the marks for the seam allowances.
*sew the two parts together. You could also appliqué the outer road to the outer buildings as an alternative.

Circles are tricky! This worked for me. Perfect 1/4 inch seams elude me!

My question actually referred to the hole diameter for the outer circle. Is that the same as the inner circle with road attached? I just wasn’t sure how to account for the seam allowance.

In a perfect world, the hole of the Tall buildings/Little houses/Skyscrapers outside ring is 42.5”—that is the hole size, seam allowance to seam allowance.

I’ve been having issues with my outer circle as well.
what is the diameter of the inside supposed to be? I think mine is way too small.

I answered this same question below, 11/24/2021, 5:59 pm.

The center of the quilt with Upper Road attached is 43.5” including seam allowances.

Thank you Barbara. I appreciate your help. Checking the seams is my next step. Thanks for the measurement of the diameter of the center with upper road attached.

Assuming the patterns were the correct size, it’s all about the seam allowances. Check quite a few of them— if they are slightly narrow, the circle will be larger than it should be.
The middle circle with the Upper Roads on the outside should measure 43.5” including seam allowances. Once your outside circle is flat, check to see your middle circle fits the open space of the outside circle. If it does, start pinning the North, South, East and West points, then half way between each of those, then halfway again, until you have pinned most every seam. Then you can start to sew.

Hello - I know someone has solved this problem...I seem to remember a question arising when we put the inner circle together with the road around its outside edge. Rather than try to scan ALL the forum posts...I'm asking...what do I need to do to get my outer circle (tall buildings 1-4 + skyscraper corners) to lie flat. Shall I take in some seams a little bit here and there? especially at the center of the curve? Shall I try to pin and begin sewing to road? Any help is appreciated. Thank you.
