Felt Valentine Envelopes

This was a project I did to continue teaching Kyla to sew.  She loves to sew and I saw a few Valentine's Day projects made with felt that I thought would be a great learning experience for her, so this is one: 

I wanted these to ft in the small mailboxes we are using this year for family valentines, so these are the measurements I used:

4 1/2 inches by 9 inches for the rectangle.
Fold up 3 1/2 inches....leaves 2 inches for the flap of the envelope.

I added the small squares of velcro and let her sew all the edges to make the envelope. 

Skills practiced: straight lines, pivoting needle at corners, back-stitching, removing pins as sewing.
