Adult Coloring PC #63 USA

This is my first time ever sending a postcard So I started coloring a postcard that i had bought ( a book of 20 postcards) and decided to measure the dimensions just for the heck of it and compared that to the usps site for postcards sizes, and I was a bit shocked. my post measures 4.75" x 6.5". Well its "too big" according to the usps sit e im just going to copy and paste here:

You may think that your mailpiece is a "postcard," because it is a single sheet of paper. But to qualify for mailing at the First-Class Mail postcard price, it must be:

Rectangular At least 3-1/2 inches high x 5 inches long x 0.007 inch thick No more than 4-1/4 inches high x 6 inches long x 0.016 inches thick If your mailpiece does not meet the dimensions above, then the Postal Service considers it a letter and letter-size postage is charged.

Well, thankfully I have a paper trimmer and was able to make the adjustments evenly, taking off a quarter of an inch on all 4 sides to make it acceptable.

I'm sure all books of postcards are different, but you may want to see how yours measures up as well

Also, I think worth mentioning, that as of Jan. 21, 2018 the price increases from 34 cents to 35 cents to mail a postcard which is a fantastic incentive to get your cards out as soon as partners are assigned or you have to add a 1 cent stamp, hope this is helpful

Is it possible to print a black & white picture onto appropriate card stock, then coloring it? Just checking.

If you use the stamps that just say POSTCARD/USA they are forever stamps and you will not have to add any postage. The ones that are for sale ate the post office now are the seashells.

Also most coloring cards are larger than postcard size so will take regular 1st class letter postage. Now 49 cents going up to 50 cents. Also same as postcard stamps if you have forever stamps will not have to add any extra no matter when you bought them.
