This is a cool pattern and I like making a few toys here and there. Squish loves it, so its a plus in my book! Before creating this pattern, I would personally learn an invisible decrease because otherwise you end up with a frog like mine, where you can see the stuffing through the huge holes made by yanking 2 stitches together. BUT the stuffing doesn't (well hasn't so far) come out, and it's a very loved frog.
The crown was just adorable and very easy to whip up. Could make a frog in some other colours and make a king & queen frog. Or a prince & princess frog. Or a whole royal frog family.
You could weight the legs and bottom with poly pellets, but I would make a little fabric (muslin) sack to put them in so a) they don't come out.. b) so they don't pose a choking hazard by coming out.. c) they don't spread through the stuffing, leaving you with a slightly lumpy and weird feeling toy.
I made my frogs arms and legs alot longer and positioned the crown a bit further back, but its easily tweaked to how you want it.
As you can see from my photo, I suck a sewing on eyes. I just can't do it. Could've used safety eyes, but that meant another trip to the craft store (normally not a problem) but it gets a bit tedious when I am taking Squish, getting him in and out of his car seat and generally taking an hour and a half for what would normally be a 20 min there and back trip.
Skill Level: Advanced Beginner. The limbs can be a little fiddly. Need an increase and decrease. Need to be confident enough to ship stitch the limbs on after stuffing.
Time Taken: From start to finish including my stopping time... about a week. In reality... probably about 3-4 hours. Was my first toy and the extra time comes from stuffing and positiong limbs.
Recommendations: Learn an invisible decreasefirst.
Verdict: Good enough for a kids toy pattern. Would happily make a few as gifts but I don't see myself turning it into a home business!
