Someone on Facebook had asked for a sewing guide and so I made one to share. Hopefully it will come in handy for someone! Designed in Inkscape. Update: They asked for a second smaller gauge in centimeters so I included it here also, (just in case someone else could use it). Also added a zip file with both SVG files in it in case someone needed it that way.
Just yesterday in a Facebook group, someone named Art ValdiviaValdivia asked for something very similar - I hope I was able to help them but they didn’t say so I can’t know for sure.
That is who I made the original of this one for. The original one I made for them was in Spanish, I then put the words in English and posted it here in case anyone else would want a copy.
Sure, the edge on the left side of the 1 to the edge on the right side of the 1 is 1". Then to the right side of the 3 is 3" and to the 5 is 5" etc, It is just a handy tool to measure when sewing.
I have built many 1 off items for things I needed around the house. the Glowforge is perfect for me to come up with things that make what I have to do much easier!
The seam allowance is the measure of the amount of material between your sewing stitch and the edge of the fabric.
Home patterns call for 5/8-inch, I always thought to give more room for error and less risk of fraying.
Professional patterns for clothes you buy in the store, most seam allowances are 1/2-inch, except around necklines and armholes, where you need less bulk, and those are 1/4-inch.
But that’s before it goes through finishing, so you’ll probably never notice it is that large.
